Disable federated buckets when etcd is namespaced (#8709)

This is to ensure that when we have multiple tenants
deployed all sharing the same etcd for global bucket
should avoid listing each others buckets, this leads
to information leak which should be avoided unless
etcd is not namespaced for IAM assets in which case
it can be assumed that its a federated setup.

Federated setup and namespaced IAM assets on etcd
is not supported since namespacing is only useful
when you wish to separate the tenants as isolated
instances of MinIO.

This PR allows a new type of behavior, primarily
driven by the usecase of m3(mkube) multi-tenant
deployments with global bucket support.

-#### Remove dependencies 
-
-  - Run `govendor remove foo/bar`

-### Making new releases 
-
-`minio` doesn't follow semantic versioning style, `minio` instead uses the release date and time as the release versions.
-
-`make release` will generate new binary into `release` directory.

+## Upgrading MinIO
+MinIO server supports rolling upgrades, i.e. you can update one MinIO instance at a time in a distributed cluster. This allows upgrades with no downtime. Upgrades can be done manually by replacing the binary with the latest release and restarting all servers in a rolling fashion. However, we recommend all our users to use [`mc admin update`](https://docs.min.io/docs/minio-admin-complete-guide.html#update) from the client. This will update all the nodes in the cluster and restart them, as shown in the following command from the MinIO client (mc):
+
+```
+mc admin update <minio alias, e.g., myminio>
+```
+
+**Important things to remember during upgrades**:
+
+- `mc admin update` will only work if the user running MinIO has write access to the parent directory where the binary is located, for example if the current binary is at `/usr/local/bin/minio`, you would need write access to `/usr/local/bin`.
+- In the case of federated setups `mc admin update` should be run against each cluster individually. Avoid updating `mc` until all clusters have been updated.
+- If you are updating the server it is always recommended (unless explicitly mentioned in MinIO server release notes), to update `mc` once all the servers have been upgraded using `mc update`.
+- `mc admin update` is disabled in docker/container environments, container environments provide their own mechanisms for updating running containers.
+- If you are using Vault as KMS with MinIO, ensure you have followed the Vault upgrade procedure outlined here: https://www.vaultproject.io/docs/upgrading/index.html
+- If you are using etcd with MinIO for the federation, ensure you have followed the etcd upgrade procedure outlined here: https://github.com/etcd-io/etcd/blob/master/Documentation/upgrades/upgrading-etcd.md

+## Caveats
+MinIO in its default mode doesn't use MD5Sum checkums of incoming streams unless requested by the client in `Content-Md5` header for validation. This may lead to incompatibility with rare S3 clients like `s3ql` which unfortunately do not set `Content-Md5` but depend on hex MD5Sum for the stream to be calculated by the server. MinIO considers this as a bug in `s3ql` and should be fixed on the client side because MD5Sum is a poor way to checksum and validate the authenticity of the objects. Although MinIO provides a workaround until client applications are fixed use `--compat` option instead to start the server.
+```sh
+./minio --compat server /data
