Implement Pagination in the GET Opportunities API

[Manvi Tyagi]

1. Use two additional query params - limit and offset
   Instead of returning all the opportunities return something like: limited_query_set = query_set[offset : offset + limit].
   An Example: if offset = 7 & limit = 20, The opportunities 7th to 27th should be returned.
   PS:
   Use
   "DEFAULT_PAGE_LIMIT" - 20
   "DEFAULT_PAGE_OFFSET", - 0
   The changes will be effectively done in /managers/opportunity/index.js in the getOpportunities function.

2. Update the API documentation accordingly inside routes/opportunity.js
