Handle a flavor create failed better

Catch FlavorCreateFailed exceptions which when flavor creation fails.
This type of flavor creation failure is caused by an internal nova problem.
Return an internal server error (500) to the user so they know
to contact their cloud provider.

VMware: add adapter type constants

Commit 6a55d4281dbdd5462eafa08321207e7f71d5ebb0 introduced
default constants. This patch creates constants for different
adapter types used.

TrivialFix

Update RESP message when failed to create flavor

The response message is unexpected(not easy to understand),if
requested resource exceeded limitation when to create flavor.
Because the error message used DB model fields but not that
used by API body. Such as following response message:
"Invalid input received: memory_mb must be <= 2147483647"
'memory_mb' is DB model field but 'ram' used in REST API

Change "memory_mb" to "ram", "root_gb" to "disk" and
"ephemeral_gb" to "ephemeral".

Fixes: bug #1350751
Preserve exception text during schedule retries

This fix preserves the exception text (as intended) when the number
of scheduling retries exceeds the maximum attempts.  We don't pop
the exception message anymore in _log_compute_error so that the
final "max attempts" error message has an opportunity to dump it
as well.

This defect caused the exception text (from the compute process) to
ALWAYS be None, thus making it difficult to triage compute errors.

Fix CellStateManagerFile init to failure

Currently, specifying a cells_config file in nova.conf causes
CellStateManager to fail and in turn stops the nova-cells service from
starting. The reason is that CellsManager creates an instance of
CellStateManager with no arguments. CellStateManager __new__ runs and
creates an instance of CellStateManagerFile which runs __new__ and
__init__ with cell_state_cls and cells_config_path set. At this point
__new__ returns CellStateManagerFile and the new instance's __init__
method is invoked (CellStateManagerFile.__init__) with the original
arguments (there weren't any) which then results in:
2014-04-29 11:52:05.240 16759 TRACE nova self.state_manager =
cell_state_manager()
2014-04-29 11:52:05.240 16759 TRACE nova TypeError: __init__() takes
exactly 3 arguments (1 given)

It seems reasonable for CellStateManagerFile to derive the
cells_config_path info for itself so I have updated the code with that
change and added unit tests to catch this bug and to check that the
correct managers are still returned

Check vlan parameter is valid

Now, we can create network with invalid vlan with nova-network.
Check if vlan parameter is greater than 4094 or less than 1.

Remove duplicated negative factors in keypair test

In test_keypair_create_fail_policy, there are two negative factors.
One is a policy violation, and another is a bad request body.
The purpose of the test is checking the policy violation, so a bad
request body is not right for this test.
This patch removes a bad request body from the test.

libvirt: Uses correct imagebackend for configdrive

When the configdrive file is created it must be moved to the
configured imagebackend, not always the raw one.

Otherwise nova can't boot an instance with a configdrive attached
when the rbd backend is configured.
