Use the firewall role and the selinux role from the vpn role

[nhosoi]

• Introduce vpn_manage_firewall to use the firewall role to manage the ipsec service. vpn_manage_firewall is set to true, by default. If the variable is set to false, the firewall configuration is disabled.

• Introduce vpn_manage_selinux to use the selinux role to manage the ports defined in the firewall ipsec service. vpn_manage_selinux is set to true, by default. If the variable is set to false, the selinux configuration is disabled.

• Add the test check task check_firewall_selinux.yml for verify the ports status.

• Add meta/collection-requirements.yml

All CI tests have passed! Is it ok to squash?

[nhosoi]

Squashed. Since all the CI tests had passed with the pre-squashed commits, we don't have to set citest?
