Add the 's' activation mode

Browse Source 
Just as 'e' means activation with an exclusive lock,
add an 's' to mean activation with a shared lock.

This allows the existing but implicit behavior of '-ay'
of clvm LVs to be specified explicitly.  For local VGs,
asy simply means ay, just like aey means ay.

For local VGs, ay == aey == asy

For clvm VGs,  ay == asy, aey == aey, asy == asy
