> In Genesis benchmark for block allocation it was found that
> BlockManager#allocateBlock call was very slow for higher number of pipelines.
> This happens because allocateBlock call gets list of pipelines with a
> particular replication type, replication factor and state. This list is
> calculated by traversing the entries of a map. This Jira aims to optimize the
> call by introducing query map in Pipeline Manager.
> The pipeline manager would keep a maintain a list of pipelines for every
> query type i.e. for every replication type, replication factor.
