New commands to work with OnlineMeetings

https://twitter.com/Lee_Holmes/status/1578417869418688512 got me thinking, we should build a new command set around this one. We could build the following commands:

• m365 teams meeting list to retrieve all online meetings; I am not sure how we can retrieve those; the only endpoint to get details is the events endpoint: https://graph.microsoft.com/v1.0/me/events but that does not support filtering on the onlineMeeting or onlineMeetingUrl, isOnlineMeeting, onlineMeetingProvider properties, so we could do something like ?$filter=isOrganizer eq true to get all meetings you have organized and loop through the URL’s in code I guess, as we need the JoinUrl to retrieve details or transcripts. #3899
• m365 teams meeting get to get details of a Teams Meeting based on the JoinUrl as described here: https://learn.microsoft.com/en-us/graph/api/onlinemeeting-get?view=graph-rest-1.0&tabs=http#example-3-retrieve-an-online-meeting-by-joinweburl #3900
• m365 teams meeting transcript list list all transcripts for a Teams meeting (needs meetingId) #3901
• m365 teams meeting transcript get to download the actual transcript (needs meetingId and transcriptId) #3908
• m365 teams meeting attendance list list all attendance reports for a Teams meeting (needs meetingId) #3907
• m365 teams meeting attendance get to download the actual attendance report (needs meetingId and transcriptId) #3909

Based on the endpoint we can also introduce m365 teams callrecord get to get recordings, I guess.

@pnp/cli-for-microsoft-365-maintainers do you by any change have some good ideas on how we can retrieve all onlinemeetings 😄?

Should we maybe rename m365 teams meeting attendance to m365 teams meeting attendancereport to be aligned with the Graph endpoint? When we look at our guidelines it states the following:

command name aligns with the underlying API where appropriate

Typically we add new permissions when we have a PR open and about to be merged. For dev, we recommend that folks use a custom AAD app or grant the missing permission to PnP Management Shell app in their tenant.
