Aditya Manthramurthy 3977d6b7bd Lock bucket while modifying its metadata (Fixes #2979) (#3019)
- When modifying notification configuration
- When modifying listener configuration
- When modifying policy configuration

With this change we also stop early checking if the bucket exists, since
that uses a Read-lock and causes a deadlock due to the outer Write-lock.

Aditya Manthramurthy d02cb963d5 Fix listen-bucket (Fixes #2942) (#2949)
Don't close socket while re-initializing notify-listeners, as the rpc
client object is shared between notify-listeners and peer clients.

Also, improves SendRPC() readability by using GetPeerClient().

Aditya Manthramurthy 6199aa0707 Peer RPCs for bucket notifications (#2877)
* Implements a Peer RPC router that sends info to all Minio servers in the cluster.
* Bucket notifications are propagated to all nodes via this RPC router.
* Bucket listener configuration is persisted to separate object layer
  file (`listener.json`) and peer RPCs are used to communicate changes
  throughout the cluster.
* When events are generated, RPC calls to send them to other servers
  where bucket listeners may be connected is implemented.
* Some bucket notification tests are now disabled as they cannot work in
  the new design.
* Minor fix in `funcFromPC` to use `path.Join`

Aditya Manthramurthy 315e66858c Add PostgreSQL notifier (#2739) (#2824)
* The user is required to specify a table name and database connection
  information in the configuration file.

* INSERTs and DELETEs are done via prepared statements for speed.

* Assumes a table structure, and requires PostgreSQL 9.5 or above due to
  the use of UPSERT.

* Creates the table if it does not exist with the given table name using
  a query like:

    CREATE TABLE myminio (
        key varchar PRIMARY KEY,
        value JSONB
    );

* Vendors some required libraries.

Harshavardhana 0a3448c8b6 events: Change event notifiers to delete and update keys. (#2742)
ElasticSearch and Redis are both treated like a database.
Each indexs are based on the object names uniquely indentifying
the event. Upon each delete event of the named object deletes
the index on elasticsearch and redis respectively.
