mysql, postgres, cassandra: change kv key to base64 encoding

Browse source 
The exisitng key-value operation for stores using mysql, postgres, and maybe cassandra are already broken.

The kv is used to store hardlink, filer store signature and replication progress.

So users using hardlink and also uses mysql, postgres, or cassandra will have broken hard links.

Users using filer.sync will need to re-sync the files.
