Kaan Kabalak a6adef0bdf Refactor bucket delete and bucket policy (#5580)
This commit adds the bucket delete and bucket policy functionalities
to the browser.

Part of rewriting the browser code to follow best practices and
guidelines of React (issues #5409 and #5410)

The backend code has been modified by @krishnasrinivas to prevent
issue #4498 from occuring. The relevant changes have been made to the
code according to the latest commit and the unit tests in the backend.
This commit also addresses issue #5449.

Harshavardhana fb96779a8a Add large bucket support for erasure coded backend (#5160)
This PR implements an object layer which
combines input erasure sets of XL layers
into a unified namespace.

This object layer extends the existing
erasure coded implementation, it is assumed
in this design that providing > 16 disks is
a static configuration as well i.e if you started
the setup with 32 disks with 4 sets 8 disks per
pack then you would need to provide 4 sets always.

Some design details and restrictions:

- Objects are distributed using consistent ordering
  to a unique erasure coded layer.
- Each pack has its own dsync so locks are synchronized
  properly at pack (erasure layer).
- Each pack still has a maximum of 16 disks
  requirement, you can start with multiple
  such sets statically.
- Static sets set of disks and cannot be
  changed, there is no elastic expansion allowed.
- Static sets set of disks and cannot be
  changed, there is no elastic removal allowed.
- ListObjects() across sets can be noticeably
  slower since List happens on all servers,
  and is merged at this sets layer.

Harshavardhana 1164fc60f3 Bring semantic versioning to provide for rolling upgrades (#5495)
This PR brings semver capabilities in our RPC layer to
ensure that we can upgrade the servers in rolling fashion
while keeping I/O in progress. This is only a framework change
the functionality remains the same as such and we do not
have any special API changes for now. But in future when
we bring in API changes we will be able to upgrade servers
without a downtime.

Additional change in this PR is to not abort when serverVersions
mismatch in a distributed cluster, instead wait for the quorum
treat the situation as if the server is down. This allows
for administrator to properly upgrade all the servers in the cluster.

Kaan Kabalak 659f724f4c Integrate existing remove bucket functionality from newux to current UI (#5289)
This commit takes the existing remove bucket functionality written by
brendanashworth, integrates it to the current UI with a dropdown for
each bucket, and fixes small issues that were present, like the dropdown
not disappearing after the user clicks on 'Delete' for certain buckets.
This feature only deletes a bucket that is empty (that has no objects).

Krishna Srinivas 14e6c5ec08 Simplify the steps to make changes to config.json (#5186)
This change introduces following simplified steps to follow 
during config migration.

```
 // Steps to move from version N to version N+1
 // 1. Add new struct serverConfigVN+1 in config-versions.go
 // 2. Set configCurrentVersion to "N+1"
 // 3. Set serverConfigCurrent to serverConfigVN+1
 // 4. Add new migration function (ex. func migrateVNToVN+1()) in config-migrate.go
 // 5. Call migrateVNToVN+1() from migrateConfig() in config-migrate.go
 // 6. Make changes in config-current_test.go for any test change

Harshavardhana 1d8a8c63db Simplify data verification with HashReader. (#5071)
Verify() was being called by caller after the data
has been successfully read after io.EOF. This disconnection
opens a race under concurrent access to such an object.
Verification is not necessary outside of Read() call,
we can simply just do checksum verification right inside
Read() call at io.EOF.

This approach simplifies the usage.

Andreas Auernhammer 79ba4d3f33 refactor ObjectLayer PutObject and PutObjectPart (#4925)
This change refactor the ObjectLayer PutObject and PutObjectPart
functions. Instead of passing an io.Reader and a size to PUT operations
ObejectLayer expects an HashReader.
A HashReader verifies the MD5 sum (and SHA256 sum if required) of the object.
This change updates all all PutObject(Part) calls and removes unnecessary code
in all ObjectLayer implementations.

Harshavardhana f8024cadbb [security] rpc: Do not transfer access/secret key. (#4857)
This is an improvement upon existing implementation
by avoiding transfer of access and secret keys over
the network. This change only exchanges JWT tokens
generated by an rpc client. Even if the JWT can be
traced over the network on a non-TLS connection, this
change makes sure that we never really expose the
secret key over the network.

Harshavardhana d864e00e24 posix: Deprecate custom removeAll/mkdirAll implementations. (#4808)
Since go1.8 os.RemoveAll and os.MkdirAll both support long
path names i.e UNC path on windows. The code we are carrying
was directly borrowed from `pkg/os` package and doesn't need
to be in our repo anymore. As a side affect this also
addresses our codecoverage issue.

Brendan Ashworth ec5293ce29 jwt,browser: allow short-expiry tokens for GETs (#4684)
This commit fixes a potential security issue, whereby a full-access
token to the server would be available in the GET URL of a download
request. This fixes that issue by introducing short-expiry tokens, which
are only valid for one minute, and are regenerated for every download
request.

This commit specifically introduces the short-lived tokens, adds tests
for the tokens, adds an RPC call for generating a token given a
full-access token, updates the browser to use the new tokens for
requests where the token is passed as a GET parameter, and adds some
tests with the new temporary tokens.

This patch also reverts previous changes which were
merged for migration to the newer disk format. We will

we wish to add protection in this release such that
future release migrations are protected.

Harshavardhana b78f6fbcc5 Do not send envVars in ServerInfo() (#4422)
Sending envVars along with access and secret
exposes the entire minio server's sensitive
information. This will be an unexpected
situation for all users.

If at all we need to look for things like if
credentials are set through env, we should
only have access to only this information
not the entire set of system envs.
