Provide pipeline support for New-RubrikSLA

[jaapbrasser]

Is your feature request related to a problem? Please describe.

Currently Set-RubrikSLA support pipeline input from Get-RubrikSLA, this behavior should also be available for New-RubrikSLA.

Describe the solution you'd like

Pipelining is a core concept of PowerShell, currently Set-RubrikSLA supports it. It would be beneficial if the logic that is used in Set-RubrikSLA gets ported to New-RubrikSLA, for example:

Get-RubrikSLA -Name 'AWS Gold DND' | New-RubrikSLA -Name 'AWS Gold DND - 2nd Edition'
