This patch adds retries to the hp hardware handler, and utilizes the MP_RETRY flag of dm-multipath. For now in the hp handler, if we get a pg_init completed with a check condition we just assume we can retry the pg_init command. We make this assumption because of incomplete data on specific check condition code of the HP hardware, and because testing has shown the HP path initialization command to be idempotent. The number of times we retry is settable via the "pg_init_retries" multipath map feature.
