Prefixing all internal functions with _
Modified subfunctions to not return values but instead manipulate multable objects
Modified all functions to not add duplicate orgs to the orgs_to_create list
* Updating the common function to respect a teams organization name
* Added can_create flag to create_org_and_teams
This made testing easier and allows for any adapter with a flag the ability to simply pass it into a function

Removed orgs_to_create from being passed into user_team functions, common create orgs code will add any team orgs to list of orgs automatically

Fix bug where we were looking at values instead of keys
Added loading of all teams if remove flag is set in update_user_teams_by_saml_attr

* Updating and adding testing
* Renamed get_or_create_with_default_galaxy_cred to get_or_create_org_...
