Invoke-IcingaCheckUNCPath - Add parameter to check as an individual user and wrong check state if share cant be acessed

[K0nne]

Hello,

I need to monitor some network shares. Those shares are only accessable for a specific subset of users.
It whould be helpful if the check could execute with individual user credentials.

Right now - even if the check cant read the target share - the check state is OK with zeroed plugin output. Whoudn't UNKNOWN be more appropriate in this case?

[OK] \\target\share\without\access
\_ [OK] Free Space: 0B
\_ [OK] Size: 0B
\_ [OK] Total Free: 0B

I tested this with the latest releases.

I have made a implementation draft of the UNC plugin, allowing different credentials.
Could you please test the linked PR?

Please ensure to delete the following file before testing the plugin:

\icinga-powershell-framework\cache\dll\IcingaUNCPath.dll

This file will be rebuild, once it was deleted before. The new DLL will then try to handle the authentication,

Example:

icinga { Invoke-IcingaCheckUNCPath -Path '\\myshare' -User 'cstein@icinga' -Password (ConvertTo-IcingaSecureString -String 'my_secret_password') -Verbosity 3 } -DeveloperMode -RebuildCache

The PR works as intended. Thank you so much :)
