ctr/sql: Providing for vol set for sqlcachesize and sqlWALsize and skip recording path

1. Providing vol set option for cache size and wal autocheck point
   so that performance can be tuned.
2. Removed recording of file path in the db. Trimming database columns.
   Path need not be stored in the db, as PARGFID, GFID, Basename is suffice
   to derive the path during migration.
