Remove any lib/baremetal usage for ironic deploy

Get rid of lib/baremetal usage so that it can be simply
deleted when that time comes:
Copy upload_baremetal_deploy function to lib/ironic;
Rename it to upload_baremetal_ironic_deploy;
Remove any $BM_* variables references from lib/ironic;
Rename $BM_IMAGE_BUILD_* environment variables to $DIB_*;
Improve logic around deploy k&r building;
Add check for $OFFLINE mode;

heat add HEAT_DEFERRED_AUTH option

Adds a HEAT_DEFERRED_AUTH, defaulted to trusts, so users can
by default take advantage of the heat trusts functionality
which provides the following benefits:
- Deferred operations (e.g autoscaling) work with token-only auth
- The password field in the heat page of horizon can be made optional
  (horizon patch pending)
- It's more secure because heat no longers stores username/password
  credentials in the DB, only a trust ID.

The previous behavior can be obtained by setting HEAT_DEFERRED_AUTH
to something other than "trusts" - the value will only be set in
the heat.conf if the value of "trusts" is found, otherwise the
heat.conf default will be used (currently "password" which doesn't
use trusts)

Fix broken if statement in lib/tls on ZSH

When using ZSH, the line `if [[ (!$cert && !$key && $ca) ]]` fails
due to a syntax error.  Instead of checking the variables as a boolean,
we can simply check if they have a non-zero length.  This works in ZSH.

Ironic: Use HOST_IP instead of SERVICE_HOST

Ironic virtual machines boot on a different network and are expected
to fetch via tftp from the conductor and callback to the API.  We
need to ensure both endpoints are accessible, even when SERVICE_HOST
is 127.0.0.1 (eg, devstack-gate).

VMware: Use multiline for cluster_name opt

cluster_name opt for vSphere driver is MultiStrOpt and currently
users are not able to set multiple values from localrc. This is
fixed by using iniset_multiline function.

Thus, new usage would be :
VMWAREAPI_CLUSTER='cluster1 cluster2 cluster3'
where c1, c2, c3 are the name of the clusters
