[EPIC] Client CLI

[Themimitoof]

Because clicodromes (french expression to designate GUIs/web interfaces with 3 millions buttons and interactions) are fun but not fast for an ops, we need to create a CLI that permit to:

• create an operation
• list operations with filters
• see the result of an operation (with a follow mode in option)
• use a synchronous tool

The CLI will use the REST API of the webserver. Multiple instances can be configured via a yaml configuration file or an another adapted format.

The CLI should be a new repository.
