Add parameter option to Request

[kmeinh]

Changes

This PR adds the functionality to add parameters on a token-renew.

In Request.swift I added a function (parameters(_ payload: [String: Any])) that returns a copy of self.
The returned object will contain all fields from before, but with an updated payload.

The functionality is very similar to BaseWebAuth.parameters(_:)

This functionality is also exposed via CredentialsManager.credentials().

Thank you for raising this PR. Looks great, just some little details.
Please add some tests in CredentialsManagerSpec.

Hi @Widcket, thanks for your feedback.

I modified the Code according to your comments and added a Test that refreshes the Token with a custom parameter. The test would fail if that Parameter is not present.

I'm not too familiar with the HTTP Library therefore I don't know if my test could be improved. I'm very open for feedback again 😄

Thank you!
