…uests This function that was provisioned in the original design of the Replication System has shown no benefits. Besides, the "duplicate" requests can't be reliably detected since the detection algorithm is time dependent.
…ation classes The class is now obsolete.
…service Extended Replication Worker's config page on the Web Dashbnoard to display connection parameters of the HTTP-based worker management services.

The new API allows embedding the partitioning tools into other applications. Migrated error handling to throw exceptions instead of calling std::exit(). Migrated the library code not to print anything directly onto std::cout. Extended the ChunkIndex API to allow extracting info on the resulting products of the translation.

The new services extend chunk allocations (placement) to include all existing replicas for the chunks in question instead of just one allocation per chunk. The extended services are meant to be used by the ingest workflows to push multiple replicas of a chunk in scenarios where the replication level is bigger than 1 and multiple replicas already exist in Qserv. The older services would fail in such scenarios. Minor refactoring on the older code. Fixed a bug in the JSON schema of of the chunks allocation service that was returning the key "location" instead of "locations". Migrated the integration test accordingly. Fixed a bug in the integration test. Migratd the documentation on the Ingest API.

Added a random delay in a range of 1 to 1001 milliseconds before making transaction reatries after InnoDB deadlocks. The specific problem to be addressed are inserts/deletions of rows into/from a table with the AUTO_INCREMENT series.
Refactoring in the HTTP modules where it was needed to implement the new feature and to prevent unnecessary code duplication.
