> One of the clusters timed out taking a snapshot for a disabled table. The table is big
enough, and the master operation takes more than 1 min to complete. However while trying to
increase the timeout, we noticed that there are two parameters with very similar names configuring
different things: 
> {{hbase.snapshot.master.timeout.millis}} is defined in SnapshotDescriptionUtils and is
send to client side and used in disabled table snapshot. 
> {{hbase.snapshot.master.timeoutMillis}} is defined in SnapshotManager and used as the
timeout for the procedure execution. 
> So, there are a couple of improvements that we can do: 
>  - 1 min is too low for big tables. We need to set this to 5 min or 10 min by default.
Even a 6T table which is medium sized fails. 
>  - Unify the two timeouts into one. Decide on either of them, and deprecate the other.
Use the biggest one for BC. 
>  - Add the timeout to hbase-default.xml. 
>  - Why do we even have a timeout for disabled table snapshots? The master is doing the
work so we should not timeout in any case.
