fix ips to 'ips' in APIRouter

Actually ips in `ips in init_only` would not be valued as True because
ips is a moudle object not a string. Fixing this to string 'ips' could
prevent potential issues and improve readability.

Ensure that exception raised in neutron are handled correctly

We are now logging exceptions so we need to use save_and_reraise.

The patch set has also added log messages for exceptions that were
raised. This will be very helpful for debugging and troubleshooting.
This is done in the following cases:
 - unable to access a port when validating networks
 - unable to find a requested floating ip

Add API schema for v3 rescue API

By defining the API schema, it is possible to separate the validation
code from the API method. The API method can be more simple.
In addition, a response of API validation error can be consistent for
the whole Nova API.

Remove admin auth when getting the list of Neutron API extensions.

Currently _refresh_neutron_extensions_cache() always authenticates
with Neutron using the configured Neutron admin credentials because
it doesn't have access to the calling context.  But it's actually
always called when a valid context exists, and the call to get the
list of extensions is not itself an admin operation.  By passing
the context down we can avoid this additional authentication step.

VMware: fix missing datastore regex with ESX driver

When using shared datastore and the ESX driver the administrator
is unable to indicate which datastore to use.

Note: there were extensive tests added for the VC driver for the
regex support. These are invoked by passing the flag for the regex
when the ESX driver is created.

Correct the state for PAUSED instances on reboot

If an instance is in the PAUSED state before the compute node is
restarted, it will be left in an inconsistent state (impossible to
delete and/or restart it) after the node boots again.

This patch adds a check in the periodic task sync_power_state so when
this situation is detected the instance is stopped and left in a state
from where it can be started again or deleted.

Correct host managers free disk calculation

Take lower of disk_least_available/free_disk_gb if they exist.

When an instance exists in the database but not on the hypervisor
(which can happen in some error cases), the 'missing' instance
is included in the calculation of 'free_gb' but not included in
'disk_available_least'.
Need to take the value that represents the minimum amount of free
disk space available.

Testing:
COMPUTE_NODES in fakes.py includes the 4 possible test cases:
    disk_least_available or free_disk_gb = free_disk_mb
        None             or     512      =    524288
        1024             or    None      =   1048576
        3333             or    3072      =   3145728
        8192             or    8888      =   8388608
   test: test_host_manager.py
           test_get_all_host_states:
             Already has existing tests looking for these
             cases - I've modifed the test data (in fakes.py)
             rather than creating new test data.
             Added check for Warning message for node 3 where
             physical disk (3333) is greater than database (3072)
         No impact on other tests.
