Revocation: remove dry-run and display options from save and verify cmds, drop default revocation file path

• Remove not very usefull --dry-run and --display options from save, and verify commands. This would relieve the tests. The intention of these options is to display a document which got generated and is to be sent directly in the command. In these commands cases, it’s an already generated file which is checked against the network. I guess, just revoke command needs to implement these options, publish, still of value if we don’t know the content of the selected file?
  • save
  • verify
  • Use idty1.pubkey instead of 6upqFiJ66WV6N3bPc8x8y7rXT3syqKRmwnVyunCtEj7o and do not duplicate lists in test_revocation_cli_save()
• For security reasons, do not gather default ./revocation.txt REVOCATION_LOCAL_PATH revocation file path definition in cwd current working directory
