Add pagination and search capabilities to the policies feature UI

[ashera96]

Describe your problem(s)

We need to enhance the current UI implementation of the Operation Level Policy Support feature to support pagination. As of now, we limit the retrieved policy count to 50. We need to avoid hardcoding this value and move to a proper pagination supported approach.

Also, since the policy list can get quite lengthy, we need to provide a searching capability within the policy list that appears under each API's Policies tab.

Describe your solution

For pagination effort:

• Globally maintained list of policies: make use of the limit and offset parameters when retrieving the policy list (note that the backend support for this already exists, and this is a UI fix).
• Per API policy list: Infinite scroll with See more ... option.

For search effort:

• Implement a search bar for the Policy List under the Policies tab. Please refer to the below attached screenshot which depicts the suggested approach for this.
