update credentials package

[Andrew-Lees11]

Update Kitura-Credentials.git dependency to take up to next major so that it works with Kitura-Credentials 2.1.0 (and hence kitura 2.2.0) and gives us more flexibility in our dependencies.

I'm fine with this, but would like @djones6's views too.

I believe this is okay.

This change allows Kitura-CredentialsHTTP to build alongside Kitura 2.1 and 2.2, as it can access the latest minor of Kitura-Credentials which bumps the Kitura-Session dependency to 3.0.

My only concern would be whether SPM resolves an existing Kitura 2.0 project in a reasonable amount of time - ie. whether the fact that it will need to roll back Kitura-Credentials to 2.0 is a problem. There is a solution, so one would hope so.

I'd suggest once this is merged and tagged, testing a kitura init project with Kitura-CredentialsHTTP included and the Kitura dependency set to .upToNextMinor(from: "2.0.0"), to make sure it resolves.

Thanks @djones6. I'm going to merge this. @Andrew-Lees11 can you tag a patch release and then immediately do the testing @djones6 suggests?
