Add support for Cisco drivers in Ironic devstack
Add support for Cisco drivers in Ironic devstack

Ironic devstack currently only supports real hardware being controlled
with the *_ipmitool drivers, this patch adds support for the two Cisco
Ironic drivers UCS and CIMC. To provide this support it deprecates the
old IRONIC_IPMIINFO_FILE replacing it with IRONIC_HWINFO_FILE, which
can support extra fields on top of the standard address, mac address,
username and password fields.
