USAGOV-1612 Setup a config split to improve developer workflow and disable devel module on production

[mdranove]

Jira Task

https://cm-jira.usa.gov/browse/USAGOV-1612

Description

Require and enable config_split module. Configure it to setup a dev split with:

1. A complete split on the Devel module.
2. A partial split on the autologout.settings to target the timeout and max_timeout config keys.

Disable this split by default, and explicitly enable the split in settings.local.php.

Additionally, enable the admin_toolbar_search module.

3. Navigate to /admin/config/development/devel.
4. The Variables Dumper setting has the "symfony var dumper" radio option selected

On dev/stg/prod

1. Navigate to /admin/config/people/autologout.
2. The Timeout and Max Timeout values are set to 1800
3. Navigate to /admin/modules. Local the devel module
4. The box is unchecked, indicating that the module is not installed.

I ran into an issue trying to import config on this one:

Configuration <em class="placeholder">user.role.content_administrator</em> depends on the <em class="placeholder">Devel</em> module that will not be installed after import. in Drupal\Core\Config\ConfigImporter->validate() (line 814 of /var/www/web/core/lib/Drupal/Core/Config/ConfigImporter.php). ```

Sure enough, the "Content Administrator" role currently has the "access devel information" role. I will ask around about whether anyone on the content team is actually using this (and why). If they're not, I'd like to have you do a PR to remove that permission, and put this one on hold until we've gotten that in front of people to make sure they're not using it. 

(If content administrators are using devel, that's another story, because they don't have local development!) 

Otherwise, it looks good. I was able to test the "dev/stage/prod" experience, roughly, by changing the local dev config setting to FALSE, so I think it'll be good.
