Add datasets counts to publishers page

[kimwdavidson]

User Story

When I go to the publisher page, I want to see how many datasets are available from each publisher, so that I know how much information I can expect to find from them.

Background

This is currently available on DKAN1, and we found in user testing that users accustomed to DKAN1 miss this feature.

Acceptance Criteria

• When I go to the publisher page

• Then I see the number of datasets for each publisher on that page

• Working downstream on Marine Scotland /groups

• Working upstream (8.x branch) on /publishers

• Working upstream to 2.0

Estimate: 8

@alexiscott This ticket has replaced #427. Can you estimate it please?

@rhabbachi Not quite there with this for Marine Scotland, but almost. I will send a message once this is ready. Thanks!

From Alex on March 28th: "Hi @rhabbachi, just a heads up that I have added a PR for Marine Scotland (which should be easier for other sites - I added a description for that to the PR.) for ticket #68 here:
https://github.com/NuCivic/data-marine-scotland/pull/27#pullrequestreview-622774801"

Looks goods for marine scotland. @alexiscott do we need to do anything for the 2.x implementation?

Yes, work still needs to happen for 2.0. I know that @dgading had some thoughts on this and the approach for data in 2.0 is cross app and will work differently.

@alexiscott @dgading Should we just create a new ticket for the 2.0 implementation or should we keep that in this ticket?

[ghost]

Moved to the backlog because we need to check with Alex if the 2.0 implementation aspect of this ticket needs to be tracked in the Support or in the Product board.

@cmugisha , that might be a question for @dgading
