Make preauthentication based on headers optional

[nbarrientos]

Pull Request (PR) description

Users might only want to configure preauthentication using request attributes, without making use of any header. The issue is that in that scenario setting the header-related settings to empty values seems to break things. I think it's probably a good idea to set them only if the relevant keys are present in preauthenticated_config.

Ready to be reviewed.

Similar to #439. I think it's fine to keep the redirectUrl setting as is.

thanks for the work @nbarrientos . can you please add tests that verify if the filecontent is present/absent?

Hi @bastelfreak

Thanks for your comments. I've added a test context to make sure that the corresponding lines are not included if the keys are not present in the config hash. The opposite case is already covered by the tests as both keys are set in the default configuration (see rundeck::config::global::rundeck_config class without any parameters on).

Btw, I'd suggest to close #439.
