ephemeral_mb is not properly set in the agent driver

[Vladyslav Drok]

When deploy_utils.parse_instance_info is called in the agent driver, it returns a dictionary with ephemeral_gb set, but IPA and ironic-lib expect ephemeral_mb, as it is done in iscsi_deploy.get_deploy_info. This causes the ephemeral partition not being created by the IPA.

A relevant log - http://logs.openstack.org/25/329625/2/check/gate-tempest-dsvm-ironic-agent_ssh-partition-image-nv/e7115a3/logs/ironic-bm-logs/node-0_console_14-06-2016-20:28:43.txt.gz#_2016-06-14_20_28_05_387, you can see that ephemeral_mb is none.

    Properly set ephemeral size in agent drivers

    This commit ensures that ephemeral_mb will be passed to an IPA
    ramdisk, as it is what is expected by both IPA and ironic-lib.

    This change also deduplicates some of the logic between
    iscsi_deploy.build_instance_info_for_deploy and
    deploy_utils.parse_instance_info methods.
