This commit allows the `forgejo-cli actions register` command to change
an existing runner's secret, as discussed in #4610.
It refactors `RegisterRunner` to extract the code that hashes the token,
moving this code to a method called `UpdateSecret` on `ActionRunner`.
A test for the method has been added.
The `RegisterRunner` function is updated so that:
- it relies on `ActionRunner.UpdateSecret` when creating new runners,
- it checks whether an existing runner's secret still matches the one
passed on the command line,
- it updates the runner's secret if it wasn't created and it no longer
matches.
A test has been added for the new behaviour.
This commit adds a new flag, `--keep-labels`, to the runner registration CLI command. If this flag is present and the runner being registered already exists, it will prevent the runners' labels from being reset.
In order to accomplish this, the signature of the `RegisterRunner` function from the `models/actions` package has been modified so that the labels argument can be nil. If it is, the part of the function that updates the record will not change the runner.
Various tests have been added for this function, for the following cases: new runner with labels, new runner without label, existing runner with labels, existing runner without labels.
The flag has been added to the CLI command, the action function has been updated to read the labels parameters through a separate function (`getLabels`), and test cases for this function have been added.
