Feature/swift format

[Dimentar]

This PR has no logic, just applied the Rules from SwiftFormat

• Added Configuration file with rules .switformat
• Created BuildPhase Run script which formats the full source code (the repo provides already the caching mechanism)
• Pay attention on GitLabRunnerProvisioner -> multiline command split

@Marcocanc for some reason I'm able to merge this PR directly without any restrictions and checks. I think you need to increase security level for this repo

Thanks for the PR! Only org members can merge directly. Will add some rules soon though
