deleteRecordings API endpoint should have an optional parameter for specific format

[MBM1607]

Problem to solve:
At the moment, there is no specific way to delete only one format of recording from the API.

My use-case is that I need both video and presentation formats initially. However, once the meeting has been reviewed, the presentation format needs to be deleted, and the video format is kept for longer to allow download.

Purposed solution:

Add a new optional parameter called format of type 'String', this can be any of the available formats (e.g video, presentation, captions etc), it can even be a comma-separated list of multiple formats.

If the format (or formats in case of comma-separated value), then only that/those should be deleted. Without passing this parameter the API will work as before ensuring backwards compatibility.

The same should be done with publishRecordings and bbb-record rebuild for consistency.
