Conservative dependency resolution

[et1975]

This PR introduces new module to be used for all install/import operations in AVS.

The Problem

PowerCLI 13.4 breaks backward compatibility and cannot be used side-by-side with packages depending on 13.3 or bellow.
At the same time the dependency specifications in the PowerCLI modules are overly open (at best specified as >= and at worst - not at all) and will try to install/import the latest, and in this case incompatible, versions and fail.

The solution

The install/import commandlets in this module will assume that only the version actually referenced is compatible with current module and will apply this logic recursively to each dependency chain.
Additional redirect map support is included for cases when dependency specification has no version at all or references invalid/non-existing version to address specific scenarios.

Explicit redirect map

Providing Microsoft.AVS.Management mapping of PowerCLI dependencies to ensure conflict-free installation/import in environments were multiple powerCLI versions are available.

Information for AVS partners

Use this module in your own testing to match the behavior of AVS.
