with this commit, the `security_groups` attribute for `os_port` will
accept either a common-delimited string or ` YAML list. That is, either
this:
- os_port:
[...]
security_groups: group1,group2
Or this:
- os_port:
[...]
security_groups:
- group1
- group2
This commit allows the `security_groups` parameter of the `os_server`
module to be either a YAML list or a common-delimited string (much like
the `nics` attribute). E.g., this:
- os_nova_server:
[...]
security_groups:
- default
- webserver
Or this:
- os_nova_server:
[...]
security_groups: default,webserver
Specifically, the stat module now has a checksum_algorithm parameter.
This lets the module utilize one of the hash algorithms available on the host
to return the checksum of the file.
This change is backwards compatible. The checksum_algorithm defaults to
sha1 and still returns its result to the stat.checksum property.
The `os_security_group` module would fail if there was no `description:`
attribute:
localhost | FAILED! => {
"changed": false,
"failed": true,
"msg": "Error creating security group larstest: Invalid input for
description. Reason: 'None' is not a valid string."
}
This commit makes the default description `''` rather than `None`.
The `os_network` module was incorrectly returning changed=False whether
or not the network was created. This commit makes the changed return
value useful.
make os_subnet behave like os_network in terms of returning information
about the created resource. With this commit, os_subnet will return the
created subnet in `subnet` and the subnet id in `id`.
When this was treated as a boolean, sphinx was leaving the Default
column on http://docs.ansible.com/ansible/ec2_module.html blank,
implying it would use AWS's default. In reality, it passes False, which
overrides the defaults at AWS (it's possible to boot an instance which
AWS claims will always have EBS optimization without it because of this
silently passed False).
