Summary

Added three new drain mode metrics to the list of multi-session fleet metrics: 'DrainingCapacity', 'DrainModeActiveUserSessionCapacity', and 'DrainModeUnusedUserSessionCapacity'.

Security assessment

This change adds monitoring metrics for operational management of multi-session fleets. While drain mode can be used for maintenance and updates, this documentation doesn't address security vulnerabilities or add security features.
