update client's get_database_details() method to return only display tagged tables

Filter for tagged tables

[MatMoore]

This isn't applying the filter as expected:

  {
    container(urn: "urn:li:container:06d3f8d11aa556b104a09cc454be2f82") {

    entities(
      input: {
        start: 0
        count: 500
        filters: [
          { field: "tags", values: ["urn:li:tag:dc_display_in_catalogue"] }
        ]
      }
    ) {
      total
      searchResults {
        entity {
          urn
          ...datasetDetails
        }
      }
    }

  }
}

fragment datasetDetails on Dataset {
  urn
  properties {
    name
  }
}

even this doesn't work:

        filters: [
          { field: "tags", values: ["garbage"], condition:EQUAL }
        ]

Need to dig into the source a bit and see if there is a bug here

[MatMoore]

It looks like the entities field is handled by this resolver: https://github.com/datahub-project/datahub/blob/master/datahub-graphql-core/src/main/java/com/linkedin/datahub/graphql/resolvers/container/ContainerEntitiesResolver.java

But this does not use the filter param, even though it is a valid field.

    final String query = input.getQuery() != null ? input.getQuery() : "*";
    final int start = input.getStart() != null ? input.getStart() : 0;
    final int count = input.getCount() != null ? input.getCount() : 20;

I'll report this as a bug but for now we can workaround it by filtering in python.
