Create repsetdata script

[kmacinnis]

Just want people to check this over, it shouldn't be merged to this branch.

LGTM

I'd recommend running ShellCheck when developing Bash scripts. There's even a handy VSCode plugin for it.

The replication_sets column is of the format {repset1,repset2,repset3}

Since the script outputs a CSV, we may want to confirm that if a variable belongs to multiple replication sets, the output does not get mangled if each replication set is considered a separate column.

@imheresamir We looked at this yesterday and multiple replication sets will be in a single column. However that was before we removed the leading or trailing { }. I'll let @kmacinnis confirm and check if this will causes issue..

Local testing results in the following:

ReplicationSets,Policy,Variable
"follower1,follower2",default:policy:root,vault-synchronizer/lob-1/safe-1/variable-1

Which could be ok depending on requirements. I would expect there to be separate lines for each replication set for each variable belonging to multiple replication sets, like this:

ReplicationSet,Policy,Variable
follower1,default:policy:root,vault-synchronizer/lob-1/safe-1/variable-1
follower2,default:policy:root,vault-synchronizer/lob-1/safe-1/variable-1

That way the ReplicationSet column can be filtered in Excel.

Couple more comments

There are numerous trailing whitespace characters in the script that are not visible in the GitHub view. Do you mind removing those? VSCode has a handy "Trailing Spaces" extension which identifies and removes them for you.
