New API Token cmdlets

[chriswahl]

Description

I would like to be able to programmatically request a new API Token as part of an automated workflow for token rotation.

Related Issue

Fixes #316

Motivation and Context

Even though a user can generate a new API Token using the GUI, there exists the need to rotate those tokens on a regular basis. This can be done through regular expiration / creation cycles, or by forcing an expiration of a token arbitrarily and creating a new token on demand.

How Has This Been Tested?

• Tested against CDM 5.0 with several variety of API Tokens generated with different tags, expiration dates, and organizations.
• Tested with Pester to ensure null and empty parameters are handled properly.

This cmdlet is only supported in 5.0 (new feature). Because of this, it appears that Pester tests for the Get-RubrikAPIData function are failing since there is no compatibility with 4.0, 4.1, and 4.2.

@jaapbrasser - I'm not sure if we can exclude different api version from the pester tests on the Get-RubrikAPIData cmdlet? Either way, other than that this code looks good to me... I'll leave the merge to you :)

Reviewed, looks good thanks for the work here @chriswahl & @mwpreston
