issue: when a block-mode pvc is created with encryption enabled
there is some space reserved for the encryption metadata.
Which doesn't allows users to write extact amount of data that
they have requested for.
solution: create pvc with extra space needed for the encryption
metadata.
The extra space is added during the CreateVolume and ExpandVolume
operations. And while returning the response remove the extra space
so the client/user gets the requested size reported.

This PR modifies the execCryptSetupCommand so that
the process is killed in an event of lock timeout.
Useful in cases where the volume lock is released but
the command is still running.
