Subject: User-Data: T2116: Added module to apply config commands at deployment

With the new `cc_vyos_userdata.py` module is possible to set in User-Data (`#cloud-config`) new parameter `vyos_config_commands`. This parameter should be a list of VyOS configuration commands that will be applied during deployment.
The module will run after the Meta-Data module `cc_vyos.py`.

Commands requirements:
 - one command per line
 - if command ending by value, it must be inside single quotes: `set some option 'value'`, `delete some option 'value'`
 - a single-quote symbol is not allowed inside command or value
The commands list produced by the `show configuration commands` command on a VyOS router should comply with all the requirements, so it is easy to get a proper commands list by copying it from another router.

Usage example (User-Data content):
```
#cloud-config
vyos_config_commands:
  - set system host-name 'demo123'
  - set system ntp server 1.pool.ntp.org
  - set system ntp server 2.pool.ntp.org
  - delete interfaces ethernet eth2 address
  - set interfaces ethernet eth2 address '192.0.2.1/24'
```
