Introduce Ci::PartitioningAnalyzer

Ref: #372598 (closed)

What does this MR do and why?

This MR introduces Ci::PartitioningAnalyzer class.

This analyzer will be used to detect queries not going through a partitioning routing table. This will help us to identify queries needed to be changed once we start using partitioning tables.

Once we will enable it, it will start raising error as below 👇

Failure/Error: raise RoutingTableNotUsedError, "Detected non-partitioned table use #{detected.inspect}: #{parsed.sql}"
Gitlab::Database::QueryAnalyzers::Ci::PartitioningAnalyzer::RoutingTableNotUsedError:
Detected non-partitioned table use ["ci_pipelines"]: SELECT "ci_pipelines".* FROM "ci_pipelines" WHERE "ci_pipelines"."project_id" = $1 AND "ci_pipelines"."id" = $2 LIMIT $3 /*application:test,correlation_id:6c4800d8-3e85-491d-867b-74c3bcf33e70,endpoint_id:GET /api/:version/projects/:id/pipelines/:pipeline_id,db_config_name:ci,line:/lib/api/ci/pipelines.rb:259:in `block in pipeline'*/
