* Add parameters for rolling updates to `docker_secret`
* Extract `remove_secrets` to its own function in `docker_secret`
* Store existing secrets in a list instead of a single secret
With this change `docker_secret` now supports the case where we store
multiple versions of a secret with the `_v123` postfix.
`absent` state implicitly handles removing these this way.
* When using `rolling_versions` don't automatically remove current secret
To make rolling updates actually work instead of failing on trying to
remove a secret that is attached to a service, use the
`versions_to_keep` parameter to remove old versions of the secret after
creating the new one. This way the secret with the new data is created
with a different name and can be attached to the service by its ID
without having to delete the previous one first which would fail if it
is already attached to a service.
* Add version numbers to newly created secrets
Attach the incremental version number to the secret name as a `_v123`
postfix where `123` is replaced with an incremental counter starting
from 1.
A label with the numeric version is also attached to the secret to ease
calculating the new version number upon change with the name
`ansible_version`.
* Return `secret_name` for docker secrets as well
* Add integration test for rolling secrets
* Update `docker_secret` documentation as per review comments
* Correctly return `docker_secret` version number as int
* Use template string for naming `docker_secrets` instead of concatenation
* Return the correct secret name on deletion failure
* Simplify `docker_secret` creation
* Add missing comma for `docker_secret` schema
* Only remove old docker secrets if `rolling_versions` is set
* Add check in `docker_secret` version parsing to handle NaNs
* Add newly created `docker_secret` to internal secret list to avoid additional deletions
* Add changelog fragment for `docker_secret` `rolling_versions` feature
* Update changelogs/fragments/270-rolling-secrets.yml
