Indy 2.1.0

This release addresses a critical latency increase when accessing content in groups that have large numbers (1000's) of constituent repositories, and the new path-mapped storage layer is enabled. In such a case, the extra latency involved with querying the Cassandra database for each constituent repository is leading to a large slow-down for content downloads.

This release addresses the problem by refactoring the content searching mechanism for groups, allowing a query for all matches of a given path in a set of constituent repositories.
