Bugfix/issue 262 page info missing on communities

[bayotheman]

🚀 Description

Included PageInfo object as an instance variable in the GetCommunityDetailsResponse component. I also included a listAllWithPages(Pageable pageable) method which returns Page<Community> object in the CommunityService interface, and implemented in the CommunitySDJpaService. This method was used in the listAllCommunities method in the CommunityController class.

📄 Motivation and Context

When you list all communities by GET /communities, you get all the communities in a communities array, you can also page them using page and size query parameters, but no pageInfo object is returned, which is required for further pagination on the front-end. This change was added to include page information to navigate the list of communities returned by the GET /communities request. https://github.com/jmprathab/MyHome/issues/262
