Content origin temp var should be the same for both scenarios

[rooftopcellist]

SUMMARY

If the pulp_settings.content_origin is set by the user, we should set the temp content_orgin var so that it is used in the token_server_dict var, otherwise if the user sets this variable it will fail on the task that sets that dict.

Without this, the following error will be seen:

TASK [Set token_server and other container default settings] ******************************** 
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'content_origin' is undefined\n\nThe error appears to be in '/opt/ansible/roles/galaxy-config/tasks/combine_galaxy_settings.yml': line 41, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Set token_server and other container default settings\n  ^ here\n"}

If the user does not set pulp_settings.content_origin, content_origin is set in the get_node_ip.yml task.

ADDITIONAL INFORMATION

This is follow-up for https://github.com/ansible/galaxy-operator/pull/137/files, which introduced this regression.
