This commits adds support for using the `--endpoint` arg when creating a
tier of type `azure`. This is needed to connect to Azure's Gov Cloud
instance. For example,
```
mc ilm tier add azure TARGET TIER_NAME \
--account-name ACCOUNT \
--account-key KEY \
--bucket CONTAINER \
--endpoint https://ACCOUNT.blob.core.usgovcloudapi.net
--prefix PREFIX \
--storage-class STORAGE_CLASS
```
Prior to this, the endpoint was hardcoded to `https://ACCOUNT.blob.core.windows.net`.
The docs were even explicit about this, stating that `--endpoint` is:
"Required for `s3` or `minio` tier types. This option has no effect for any
other value of `TIER_TYPE`."
Now, if the endpoint arg is present it will be used. If not, it will
fall back to the same default behavior of `ACCOUNT.blob.core.windows.net`.
- Adds versioning support for S3 based remote tiers that have versioning
enabled. This ensures that when reading or deleting we specify the specific
version ID of the object. In case of deletion, this is important to ensure that
the object version is actually deleted instead of simply being marked for
deletion.
- Stores the remote object's version id in the tier-journal. Tier-journal file
version is not bumped up as serializing the new struct version is
compatible with old journals without the remote object version id.
- `storageRESTVersion` is bumped up as FileInfo struct now includes a
`TransitionRemoteVersionID` member.
- Azure and GCS support for this feature will be added subsequently.

With this change, MinIO's ILM supports transitioning objects to a remote tier.
This change includes support for Azure Blob Storage, AWS S3 compatible object
storage incl. MinIO and Google Cloud Storage as remote tier storage backends.
Some new additions include:
- Admin APIs remote tier configuration management
- Simple journal to track remote objects to be 'collected'
This is used by object API handlers which 'mutate' object versions by
overwriting/replacing content (Put/CopyObject) or removing the version
itself (e.g DeleteObjectVersion).
- Rework of previous ILM transition to fit the new model
In the new model, a storage class (a.k.a remote tier) is defined by the
'remote' object storage type (one of s3, azure, GCS), bucket name and a
prefix.
* Fixed bugs, review comments, and more unit-tests
- Leverage inline small object feature
- Migrate legacy objects to the latest object format before transitioning
- Fix restore to particular version if specified
- Extend SharedDataDirCount to handle transitioned and restored objects
- Restore-object should accept version-id for version-suspended bucket (#12091)
- Check if remote tier creds have sufficient permissions
- Bonus minor fixes to existing error messages
