Review comment:
relooking at this logic, earlier there were no way to specify renewer,
now that I have added way to specify renewer, we have to fallback to default
implementation ( which is to take renewer = `getMRTokenRenewerInternal(new
JobConf()).toString();` ) so it will fall into original implementation if user
does not specify renewer. we can als added an overloaded method
`getAllFSTokens` that does not take renewer at all to make it look as earlier.

> Key: GOBBLIN-1308

> Project: Apache Gobblin
> Issue Type: Improvement

> Reporter: Jay Sen
> Priority: Major
> Fix For: 0.16.0
>
> Time Spent: 3h

> Gobblin's hadoop tokens/ key management :
> Problem: Gobblin only maintains local cluster tokens when key management is
> enabled. and does not have capability to manage tokens for remote hadoop
> cluster. ( based on my conversation with many folks here, the token files can
> be made available externally. but that would require that external system
> running on cron or something )
> Solution: add remote cluster token management in Gobblin. where remote
> clusters key can be managed same way it manages the local clusters keys.
>
> Config looks like following
> ( Changes the enable.key.management config to key.management.enabled )
>
> {code:java}
> gobblin.hadoop.key.management {
> enabled = true
> remote.clusters = [ ${gobblin_sync_systems.hadoop_cluster1},
> ${gobblin_sync_systems.hadoop_cluster2} ]
> }
> // These Gobblin platform configurations can be moved to database for other
> use-cases, but this layout helps make the platform moduler for each
> connectors.
> gobblin_sync_systems {
> hadoop_cluster1 {
> // if Hadoop config path is specified, the FileSystem will be created based
> on all the xml config provided here, which has all the required info.
> hadoop_config_path = "file:///etc/hadoop_cluster1/hadoop/config"
> // If hadoop config path is not specified, you can still specify the
> speecific nodes for the specific type of tokens
> namenode_uri = ["hdfs://nn1.hadoop_cluster1.example.com:8020",
> "hdfs://nn2.hadoop_cluster1.example.com:8020"]
> kms_nodes = [ "kms1.hadoop_cluster1.example.com:9292",
> "kms2.hadoop_cluster1.example.com:9292" ]
> }
> hadoop_cluster2 {
> hadoop_config_path = "file:///etc/hadoop_cluster1/hadoop/config"
> namenode_uri = ["hdfs://nn1.hadoop_cluster2.example.com:8020",
