> Avoid transaction state cache refresh on co-procesor startup

> Transaction state cache, on startup, refreshes the transaction snapshot from
> HDFS. The transaction state cache startup is called during HBase co-processor
> startup. The refresh of the transaction snapshot can block, thus blocking the
> co-processor startup.
> The subsequent transaction snapshot refreshes happen in the background. Also
> - there is no guarantee that a snapshot will be present during the refresh on
> startup. Hence it is okay not to refresh the snapshot during snapshot, but do
> it in background.
