get(key, options) {
        return this._doGet(key, options);
    }
IMPORTANT:
We store settings with a type and a key in the database.

{
  type: core
  key: db_hash
  value: ...
}

But the settings cache does not allow requesting a value by type, only by key.
e.g. settingsCache.get('db_hash')

Get a key from the this.settingsCache
Will resolve to the value, including parsing JSON, unless {resolve: false} is passed in as an option
In which case the full JSON version of the model will be resolved

@param {string} key
@param {object} options
@return {*}
