Move google_tag configuration from optional to install

[jcsparks]

There's 2 google_tag configuration files that are currently in config/optional :

1. google_tag.container.GTM-M3DX2QP.65de22067902c7.57590325.yml
2. google_tag.settings.yml

The first one should be moved to config/install. This is the configuration for the main CU GTM container and we want that to be the same across all of the sites.

The second one has configuration for tags that should be configured on the site. This one should remain in config/optional so that we don't overwrite any custom CTM container tags that are added after installation.

Currently all of the sites are still set to apply the GA code to all users despite the config saying that it should only be for the anonymous user because this config is in optional. Moving to install should resolve that issue.
