Allow extra parameters when playbook is defined in configuration/settings file

[shatakshiiii]

Summary:

With this, all the parameters that are not directly supported by ansible-navigator and usually used via a -- delimiter, can also be used when playbook is defined in the navigator's settings file.

This will allow ansible-navigator run to support extra parameters when playbook is specified in the configuration (instead of command itself)

Example: ansible-navigator run -- -e my_var=value

When configuration can be something like :

---
ansible-navigator:
  ansible:
    playbook:
      path: "playbooks/ping.yml"

Fixes: #1437
