Improve Microsoft Sentinel export process

[0xFustang]

Description

In this PR, we're improving Microsoft Sentinel export process but also:

• Ability to export rules to a restricted list of Microsoft Sentinel workspaces (--mssp and --export mode)
• When possible, add the MITRE ATT&CK tactics and techniques to the rule
• Add new environment variables to override the authentication mode for Microsoft Sentinel and Microsoft XDR
