3PAR: Set the right minimum client version

The 3PAR driver currently has a mismatch between the minimum version
reported in the driver-requirements.txt file and
cinder/volume/drivers/hpe/hpe_3par_common.py.

Currently the minimum version enforced by the code is 4.2.0, but that is
not correct for the iSCSI driver, since it's using the
"is_primera_array" method which was first included on 4.2.10 [1].

This patch updates the driver-requirements file to match the minimum
version for iSCSI, and also enforces version 4.2.10 for both drivers,
iSCSI and FC, for simplicity's sake.
