Add a test equivalent to default_log_levels

This is to mainly kill the migrate script logs
but can be used to quieten down any log.
Also the migrations were not using the FakeLogger
so now both are using the same mechanism.

Using new attribute schema for all resources

Currently resources use old style of attribute schema. For example:

    attribute_name: _('Description')

This patch contains changes to migrate for new attribute Schema class.
For example:

    attribute_name: attributes.Schema(_('Descriprion'))

Fix stack_resource's handle_adopt

- This changes a call from (non-existing) _to_parameters()

  create_with_template()
- Also add a missing check_adopt_complete to stack_resource

Do not validate constraints in schema constructor

This patch moves validation of constraints out of the constructor of
schema objects into a separate method that can be invoked on the
schema objects after creation. This gives us more control over when
validation shall be invoked.

This patch fixes an issue with custom constraints that could not be
validated when having a default value, since they require the RPC
context to be present. However, the context was not present in the
places where needed.
The short-sighted fix would have been to change a lot of method
signatures to pass the context properly, but that did not seem to be
really clean. The better fix seemed to be to move validation into
a separate method that can be invoked with the proper context. This
will also give us more control on when we do validation, and which
validation we do.

This patch
Closes-Bug: #1314240

This patch will also enable to fix
Partial-Bug: #1314401

For that bug it will be necessary to switch off validation under
certain conditions, which was not possible before when doing
validation right in the constructor.

Refactor neutron resources lookup

This patch moves new neutron resources resolution methods
of basic neutron resource to a separate module neutron_utils
(similar to nova_utils) for easier usage in other parts of the code.

Restore resource_id from backup_stack when delete

When UpdateReplace is occured, the resource is moved to backup_stack,
and create new one. Then, resources which has dependency for updated
resource will be moved to backup_stack. If the creation of update is
failed, dependencies between backup_stack and exist_stack will exist.

Heat deletes backup_stack before deleting exist_stack. The dependency
still exists, so it will be failed. Thus, add behavior that restores
resource_id in the backup_stack when the stack is deleted.
