Feat: allow using terratag as a validation tool - add dryrun

[TomerHeber]

Added a new dryrun mode that checks if all resources are tagged. If a resource isn't tagged, it returns 1 exit code.

resolves #178

@TomerHeber could you please add some screenshots here or something like that so I could understand the flow and it how it looks like to the user? Thanks

talked in Slack - will change to verifing for specific tags - If tags are passed it will check for these tags... otherwise just in general...

@TomerHeber what's the status here?

[TomerHeber]

@avnerenv0 - I have been busy with the provider. I will get back to it when things cool down on the provider side.

@TomerHeber it's Passover soon I have to close this :)
