Add a Get-MgChangeLog cmdlet

The Graph team just redesigned their change log page (not released yet), and added a bunch of filters to allow users to get the latest change log for various products, etc. so that they can see a filtered view, plus added an RSS feed for the ChangeLog. That's all great, but I'm a command-line oriented guy, and would love to see a Get-MgChangeLog cmdlet that does not require authentication that allows me to retrieve the entire change log or a filtered change log by using parameters to filter the data right in PowerShell. This would allow me to plug that cmdlet into my existing toolchain, solutions I have built on the Graph module bundle, etc. so that I can surface the change log details where it matters most in a manner that is useful to whoever needs the information.

Inizia esaminando la pagina Change Log riprogettata e il relativo feed RSS, quindi individua i punti di ingresso del repository per aggiungere un cmdlet PowerShell. Conferma i filtri disponibili e i requisiti per l’accesso non autenticato; il lavoro è completato quando Get-MgChangeLog può recuperare l’intero registro delle modifiche e i risultati filtrati senza autenticazione. Nell’issue non sono indicati file o test.
