ManagementConnection - Added GetCimSession method

[FriedrichWeinmann]

This adds a GetCimSession method to the CM Connection class.

The key reason for this update is to improve interop between the read-only Computer Management component and the external use of Invoke-CimMethod. This enables the transparent passing through of session configurations and policies and will allow commands such as Restart-DbaService to respect proxy settings or protocol preference.

This includes the ability to execute against localhost without the WinRM Service running.

Notes

• As this only adds a method without changing any existing code, this has no impact on anything (yet)
• In order for this change to have an effect, it must then later be called from other functions in dbatools. But the library update should go first to avoid breaking tests, rather than updating the functions concurrently.
