Use GraphQL Pagination Properly

[lepsalex]

Currently the main table will load 100 rows of data and handle the pagination in the front-end, this can be moved to the graphql query to save on data transfer.

• Use the standard GraphQL pagination model: https://graphql.org/learn/pagination/. We donts need full hits/edges/node

• Make a new ticket in api repo with info above
  ---- need a results object to return total
  ---- 1 layer of nesting for all hits (entities ex file + runs+ analysis)

• Keep the existing GraphQL; add a new v2 path https://api.rdpc-qa.cancercollaboratory.org/v1/graphql

• Can switch over services to /v1 one by one [workflow node, workflow ui, workflow management, workflow graph, aggregator, model-tee]

• Update this section in UI as well; may need to reach out to @lepsalex for aggregation endpoints.
