keep connection open to API

[Rocco83]

There are currently several call to katello/foreman API, and, in my understanding, every call is asking for a new authentication.
It would be a good improvement to have one initial "login", perform operations, and "logout" at the end of the script.
In example, in case of LDAP connection Foreman/Katello give sometimes 500 error in authentication.
This can be a workaround.

What do you think about it?
Do you have any suggestion on how to handle the 1st time auth with Katello/Foreman API?
I can for sure work on the PR.

The API currently does not support any kind of non user/pass login:

Until this is resolved, I do not really see a way for bootstrap to fix your issue.

Keeping the TCP conenction open could also help, but that would pull in way too much state into bootstrap.
