[ASP-5649] Enable positional arguments on "get-one" commands on Jobbergate-cli

[fschuch]

What

All the Jobbergate commands that select one entry do it by command line options like --id, or --identifier, for instance:

jobbergate applications get-one --id <application_id> ...
jobbergate applications get-one --identifier <application_identifier> ...

Since the identification is required when selecting a given entry, it can be changed to a positional argument. In this way, it can be provided right after the command with no need to type --id or --identifier every time. For instance:

jobbergate applications get-one <application_id> ...
jobbergate applications get-one <application_identifier> ...

This was just an example on jobbergate applications get-one, but this enhancement can also be extended to many other commands.

Why

As a Jobbergate user, I want a simplified way to select entries on the jobbergate commands, so that my experience using the cli is less typing intensive.
