- Adds an interface to update in-memory bucket metadata state called
BucketMetaState - this interface has functions to:
- update bucket notification configuration,
- bucket listener configuration,
- bucket policy configuration, and
- send bucket event
- This interface is implemented by `localBMS` a type for manipulating
local node in-memory bucket metadata, and by `remoteBMS` a type for
manipulating remote node in-memory bucket metadata.
- The remote node interface, makes an RPC call, but the local node
interface does not - it updates in-memory bucket state directly.
- Rename mkPeersFromEndpoints to makeS3Peers and refactored it.
- Use arrayslice instead of map in s3Peers struct
- `s3Peers.SendUpdate` now receives an arrayslice of peer indexes to
send the request to, with a special nil value slice indicating that
all peers should be sent the update.
- `s3Peers.SendUpdate` now returns an arrayslice of errors, representing
errors from peers when sending an update. The array positions
correspond to peer array s3Peers.peers
Improve globalS3Peers:
- Make isDistXL a global `globalIsDistXL` and remove from s3Peers
- Make globalS3Peers an array of (address, bucket-meta-state) pairs.
- Fix code and tests.
