Description

Summary of changes:
This pull request includes several changes to the src/SdnDiagnostics.psm1 and src/SdnDiagnostics.psd1 files, focusing on enhancing the configuration state retrieval, data collection, and log management functionalities. The most important changes include adding new parameters, modifying existing functions to handle multiple roles, and improving log collection processes.

Enhancements and new functionalities:

• Added a new cmdlet Get-SdnLogFile to the module manifest file src/SdnDiagnostics.psd1.
• Introduced a new Role parameter to the SdnDiagnostics configuration in src/SdnDiagnostics.psm1 to define the current role(s) for the node.

Improvements to configuration state retrieval:

• Modified the Get-SdnConfigState function to accept multiple roles and set the Role parameter as optional, defaulting to the global configuration role. [1] [2]

Enhancements to data collection:

• Updated the Start-SdnDataCollection function to handle multiple roles and nodes, including validation of WinRM connectivity and limiting data collection to a specified number of nodes per role. [1] [2] [3] [4]
• Improved the log collection process by separating the collection of diagnostic logs, event logs, and audit logs, and ensuring logs are collected from the appropriate nodes based on their roles. [1] [2] [3] [4]
