feat(anta): NetBox as an inventory source

[JulioPDX]

Description

Initial implementation to get NetBox as an inventory source. This has a lot of areas where it could be improved (logging, syntax, naming) but I hope this initial PR can get the idea implemented.

Example using the public NetBox demo instance:

> anta get from-netbox -nbi https://demo.netbox.dev -nbt 1092017ee4dba8515d37a6b0ab104cc5978331c7 -o test.yml
[16:20:14] INFO     Building inventory from netbox instance file          commands.py:119
                    'https://demo.netbox.dev'                                            
[16:20:15] INFO     ANTA inventory file has been created: 'test.yml'         utils.py:130

Still TODO:

• Add tests
• How to set verify to False as a parameter and pass pre-checks
• Documentation
• Improved Typing
• Add pynetbox as an optional install

Fixes #257

Also need to look at making the filter or search more dynamic. For example, maybe someone only wants the inventory from site=ny-dc-1.

Good start! Thanks for taking this over! will need to add tests and documentation for this

1/ Given that you are in the from-netbox command context I dont think you need to add nb prefix to the options (except if it makes a lot of sense)

2/ the default for security should always be True ;)

3/ I think (and we may not be doing this everywhere) that you don't need required=False as it is the default in click. Same for default=None

Lets make a better error message telling what to instal pip install anta[netbox]?

[gmuloc]

need to be more specific on which Exception you can get
