Add "Automatic Based on Content" option on ipsec myid_type and peerid_type

[mdepedrof]

In IPSec VPN Phase1 to identify peers and my side, in Gui I have the option to specify a String "Automatic Based on Content". Unfortunely i cant use this option with ansible pfsensible.core.pfsense_ipsec_aggregate or pfsensible.core.pfsense_ipsec

Is your feature request related to existing pfSense functionality that is missing from the API? Please describe.
Searching in the gui (/vpn_ipsec.php), I have seen that the option I am talking about is marked as auto

Describe the solution you'd like
the best solution would be to allow in the array of options to use the option auto.
