Inconsistency between `property` flags and `cpcodes` flags

[terodox]

There are several inconsistency in flag usage between the property commands and the cpcodes commands.

In the property flags we use:
--config anywhere in the command
--group for group id
--contract for contract id

In the cpcodes flags we use:
--config must be used globally prior to subcommand
--groupID for group id
--contractID for contract id

This inconsistency leads to a very confused user experience from the CLI.
