Add subid option to select the sssd profile with-subid.

This is an ansible-freeipa update for the freeipa RFE:
https://pagure.io/freeipa/issue/9159


"`ipa-client-install` should provide option to enable `subid: sss`
in `/etc/nsswitch.conf`".

This option allows to configure authselect with the sssd
profile + with-subid feature, in order to have SSSD setup as
a datasource for subid in /etc/nsswitch.conf.

The default behavior remains unchanged: without the option,
/etc/nsswitch.conf keeps the line subid: files
