Avoid explicit reading of /etc/salt/minion (bsc#1220357)

What does this PR do?

Parcial backport of https://github.com/saltstack/salt/pull/65696 with https://github.com/saltstack/salt/pull/65696/commits/d54407ba6dc664e5e5f3f613e27ae24f828c9648 from upstream PR only.

Upstream PR is messy and contains a list of changes not related to the original description. I'm closing previous PR https://github.com/openSUSE/salt/pull/641 in favor of this one.

In some cases salt-call on the salt-ssh client side is rereading /etc/salt/minion explicitly what doesn't make any sense.
