Fixes #1304 Ability to add/edit deployment ids though the django admin panel

[jonespm]

This draft is working so far, but currently it's either/or. You define a config in the config file or in the admin panel.

This presents somewhat of a chicken/egg problem. Since you'd need to have the entry in the database or have a local admin account to login to add the initial configuration. I'm not sure the best way to handle this yet.

We could either

1. Try to combine the ToolConfDict and DjangoDbToolConf so you have to define something in the config file first which would allow an initial launch. But this initial launch wouldn't be editable.
2. Have some type of management command to load an initial json into the database? Maybe extend or be based on the current createkeys command to instead create keys and create a tool on the CLI? It could still generate the keys, saving a step?
3. Require other schools to leave the "ENABLE_BACKEND_LOGIN": true at least initially so it can be configured then maybe turn it off?

I'm somewhat leaning against solution 1, because you can't modify the config JSON that's kind of a negative. Unless the software inserted that initial value into the database? Perhaps as a 4th idea similar to 1

4. If there is no data in the database but there is configuration data in the config file, populate the Db with the ToolConfDict data. (This would still require keys generated though so not super ideal)

5. Provide configurable SQL queries to populate the initial data in the database.
