PR Summary

• Modify get behavior to warn instead of error if any input is provided for filtering so DSC's synthetic test can be utilized
• Add trace level and formatting options for easier debugging

• Expand set Pester tests to cover various argument types and invocation from DSC

Pull request overview

This PR expands the sshdconfig set capability to handle various SSH configuration argument types beyond simple strings. It modifies the get behavior to warn instead of error when input filters are provided (enabling DSC synthetic tests), adds configurable tracing with level and format options, and implements comprehensive formatting functions for different value types including match blocks.

Key changes:

• Changed get command behavior from error to warning when input filters are provided
• Added trace level and format configuration options (CLI flags and environment variable support)
• Implemented format_sshd_value() and format_match_block() helper functions to properly format booleans, arrays (with comma/space separation), numbers, and match blocks
• Split MULTI_ARG_KEYWORDS into comma-separated and space-separated lists for proper formatting
