Add slices items to search index mapping and update search document test to represent what we use it for in V3 orders to test more edge cases

Added DocumentStore() to search, which will be used in V3 to store orders in OpenSearch then do text searches on them

More cleanup, remove clutter, add to api-logs, sqs-logs possible, action list in api-logs, runtime control possible

See merge request uafrica/go-utils!8

Cleanup and better api-logs (and sqs also possible) with actions list capturing significant actions taken during handlers (off by default)

Restructure and improved logs and audit

See merge request uafrica/go-utils!7

Restructure mainly queues to separate consumer from producer, because consumer is a service, but service must be able to produce, which caused cyclic dependencies. Now audit and logs can use a producer to send SQS events, and service can use logs and audits.

Search package improvements to retrieve documents with text searches from OpenSearch

See merge request uafrica/go-utils!6

Add search client for OpenSearch to log and query API events

See merge request uafrica/go-utils!5
