[FEATURE] Setting to allow job table status updates for anonymous users

[swainn]

Is your feature request related to a problem? Please describe.
The job table in an app with open portal mode enabled doesn't update b/c the update status API is protected by a login required decorator. For example, update_row:

tethys/tethys_gizmos/views/gizmos/jobs_table.py

Line 236 in c24902e

@async_login_required

Describe the solution you'd like
Honor open-portal mode setting or provide another setting to allow retrieval of jobs status without being logged in.

Options:

1. Remove the async_login_required on status/read-only endpoints
2. Create an async version of the Tethys login_required which honors open portal mode.
