snapshot: append timestamp with snapname

Appending GMT time stamp with snapname by default.
If no-timestamp flag is given during snapshot creation,
then time stamp will not append with snapname;

Initial consumer of this feature is Samba's Shadow Copy
feature. This feature allows Windows user to get previous 
revisions of a file. For this feature to work snapshot 
names under .snaps folder (USS) should have timestamp in 
following format appended:
@GMT-YYYY.MM.DD-hh.mm.ss

PS: https://www.samba.org/samba/docs/man/manpages/vfs_shadow_copy2.8.html

This format is configurable by Samba conf file. Due to a 
limitation in Windows directory access the exact format 
cannot be used by USS. Therefore we have modified the file 
format to:
_GMT-YYYY.MM.DD-hh.mm.ss

Snapshot scheduling feature also required to append timestamp 
to the snapshot name therefore timestamp is appended in 
snapshot creation itself instead of doing the changes in 
snapview server.
