* Code formatting (indentation and white space) fixes for improved PEP8 conformity.
* Remove redundant backslashes inside parentheses.
* Test for object identity should be 'is not None'.
* Test for membership should be 'not in'.
* Fit docstring to the PEP8 79 character limit.
* Use forward compatible Python 2.6+ 'except .. as' syntax for exception handling.
* Support libcloud > 0.15 'metadata' argument format.
nics is a great flexible parameter, but it's wordy. Shade now supports
a simple parameter too, which is just "network" and takes a name or id.
Add passthrough support.
In addition to supporting booting from a pre-existing volume, nova and
shade both support the concept of booting from volume based on an image.
Pass the parameters through.
Shade supports boot-time attachment of additional volumes for OpenStack
instances. Pass through the parameter so that ansible users can also
take advantage of this.
If this is not set, Ansible parses the parameter as a string.
This is fine if the parameter is not provided by the caller, but
if it is set to False or True explicitly, ec2_vol receives this as
the string 'False' or the string 'True', both of which are truthy.
Thus, without this fix, setting the parameter results in encryption
always enabled.
Previously, the `promote` command in the `rds` module would always return OK and never actually promote an instance. This was because `promote_db_instance()` had its conditions backwards: if the instance had the `replication_source` attribute indicating that it **was** a replica, it would set `changed = False` and do nothing. If the instance **wasn't** a replica, it would attempt to run `boto.rds.promote_read_replica()`, which would always fail.
'exact_count' and 'state' are mutually exclusive options they should not be in the following examples:
- # Enforce that 5 running instances named "database" with a "dbtype" of "postgres" example and
- # Enforce that 5 instances with a tag "foo" are running
The min_disk and min_ram parameters were not being passed to
the shade API. They also need to be integer values. Also
updated the description of these parameters for better
clarification.
