Project config importing and exporting

[idagelic]

Is your feature request related to a problem? Please describe. Add daytona project-config import and daytona project-config export commands to create/use JSON files to manage project configs. The import command should take a mandatory file location path argument. The export command should take the first argument as the project config name or if run without arguments should open the TUI to prompt the user for which config to export.

Exports should by default go to the folder "exports" -> "project-configs" inside of the main daytona directory and be named by the project config name. Some way/command to clean the exports up should also be implemented
