Added Scan management logic to perform Audit scans using Jfrog Cli

[kerenr-jfrog]

• Implemented ScanManager to perform an audit scan using the Jfrog CLI.
• In case of multiple projects, the scan will be performed by multiple threads, each one will run a background process for running an audit scan.
• Added functionality to prevent new scans from starting if an existing scan is already in progress, ensuring orderly and non-conflicting scan operations.
• Created the ScanCache class to aggregate scan results and maintain persistence, ensuring that results are consistently displayed in the UI.
• Removed logic of performing a scan when the plugin is loaded.
• Added a checkbox in the settings window to enable the generation of debug logs if necessary.

Nice! check out my comments. In addition:

1. make sure you format the changes, I can see some missing spacing in some places
2. is it possible to start adding tests at this stage?
