* Revert change to docker_common as it's not as good as the try: except fix
* limit docker_volume fix to ImportErrors
* fix docker_secret i nthe same way
* Remove docker_secret from import tests
Consolidate the module_utils, constants, and config functions that
convert values into booleans into a single function in module_utils.
Port code to use the module_utils.validate.convert_bool.boolean function
isntead of mk_boolean.
* Add flag to Docker pull_image to know when the image is already latest
Whenever the flag pull is set to 'yes' the resource is always defined
as 'changed'. That is not true in case the image is already at the
latest version.
Related to ansible/ansible#19549
* Docker pull_image does not change status if the image is latest
This prevents an exception from occurring when an image has no name. While images normally have names it is possible, at least on older versions of Docker, for an image to "lose" its name during a failed `docker rm`.
