Remove requiretty from sudoers
Remove requiretty from sudoers

Requiretty in the sudoers files just makes things
more complicated and causes unexpected trouble. [1]

Fedora get rid of this mess since long [2].

Interesting discussions are also here [3] and "little"
security benefit explained here [4].

Let's remove it from our undercloud nodes,
in order to avoid interfering with CI.

Requiretty must be disabled in all Ansible jobs using os-cloud-config
as they might be affected too, until upstream fix proposed
at https://review.openstack.org/#/c/350004/ will be merged.
