LU-1770 ptlrpc: introducing OBD_CONNECT_FLOCK_OWNER flag

After applying flock policy fix into the 1.8 users met with an issue
when 1.8 clients with a fixed flock policy recognized incorrectly by
2.x servers.
This flag is intended to present 1.8 clients with fixed flock policy
to let 2.x servers make flock policy recognition correctly.
Patches with functionality changes were attached on review in LU-1575
