pool: remove hidden defaults for rh/rm/sh operations

fixes commit 84f1da6

Motivation:
Site commit 84f1da6 we have expected that the default HSM timeout values
for store, restore and remove are gone. Hoever, pool.barch comes with a
default setup file, that initializes this values and a pool gets default
timeouts even if pools setup files doesn't defined them.

Modification:
remove obsolete defaults.

Result:
expected behaviour on pool restart.
