Paginate Policies API

[mostlikelee]

the Policies page and GET /policies API slow significantly when policies are added due to slow database query performance.

The /policies APIs must paginate to limit queries on the policy_membership table speed up response times.

The frontend Policy tab needs to utilize pagination options (page and per_page) on the existing /policies endpoints to limit the number of policies a user receives from an API request to 20.

New params for existing global policies and team policies endpoints:

• page
• per_page
• query
• order_key
• order_direction

New APIs required:

• Add a count endpoint for global policies
• Add a count endpoint for team policies

@mostlikelee From the slack conversation earlier I believe the /api/v1/fleet/global/policies/count api documentation is inaccurate and instead should be /api/v1/fleet/policies/count

I checked a number of combinations using the new policies parameters and they appear to be working great!

API's gentle flow,
Paginate policies, ease,
In cloud city's glow.
