Proposed changes

cv_container now support option to remove configlet(s) from container by
using a new optional keyword. Meantime, this keyword allows user to also
filter configlets to attach to container

Module Behavior:

• Add new optional input: configlet_filter (list)
• Addition process:
  • if configlet from intended match filter: configlet is attached
  • if configlet from intended does not match filter: configlet is
    ignored
  • configlet_filter = ['none'] filtering is ignored and configlet is
    attached
• Deletion process:
  • if configlet is not part of intended and filter is not matched: we do
    not remove it
  • if configlet is not part of intended and filter is matched: we
    detach configlet.
  • configlet_filter = ['none'], configet is ignored and not detached

Well knows filter value:

• none: fallback mechanism to merge (no deletion and add everything from intended)
• all: match all

Default value: `configlet_filter=['none']

How to test

• Attach configlets to containers

CVP_CONTAINERS:
  DC1_FABRIC:
    parent_container: Tenant
  DC1_L3LEAFS:
    parent_container: DC1_FABRIC
    configlets:
      - GLOBAL-ALIASES
      - GLOBAL-ALIASES2

With tasks:

---
- name: Rebind configlet based on basic AVD
  hosts: cv_server
  connection: local
  gather_facts: false
  collections:
    - arista.avd
    - arista.cvp
  vars:
    container_root: 'DC1_FABRIC'
    configlets_prefix: 'DC1-AVD'
    device_filter: 'DC1'
    execute_tasks: false
  tasks:
    - name: 'Refreshing facts from CVP {{inventory_hostname}}.'
      arista.cvp.cv_facts:
      register: CVP_FACTS

    - name: "Building Containers topology on {{inventory_hostname}}"
      arista.cvp.cv_container:
        topology: '{{CVP_CONTAINERS}}'
        cvp_facts: '{{CVP_FACTS.ansible_facts}}'
        # configlet_filter: ['all'] == 'none'

• Remove Container attachement

      arista.cvp.cv_facts:
      register: CVP_FACTS

    - name: "Building Containers topology on {{inventory_hostname}}"
      arista.cvp.cv_container:
        topology: '{{CVP_CONTAINERS}}'
        cvp_facts: '{{CVP_FACTS.ansible_facts}}'
        configlet_filter: ['all']
