Enable Parameter Parsing with Mongo 3.6 Cluster Connection Protocol

[BenedictRasmussen]

See this issue. This PR makes parameter parsing for config values check the protocol. If the protocol is Mongo 3.6's new cluster connection protocol (mongodb+srv), create the associated connection string (essentially just dropping the port.)

Resolves #63

Thank you very much for the PR. It looks very good! Just one suggestion.

Please move the config object to test case should return valid DB connection URI with Mongo 3.6 protocol:

  it('should return valid DB connection URI with Mongo 3.6 protocol', () => {
      const dbConfig: SeederDatabaseConfig = {
            ...
      };
      const expectedUri = 'mongodb+srv://127.0.0.1/database';
      const uri = databaseConnector.getDbConnectionUri(dbConfig);
      expect(uri).toBe(expectedUri);
  })

Also, please rename it to simply dbConfig.

This should be addressed now. Thanks or the feedback!
