Loki - v2.9.0

Grafana Labs is excited to announce the release of Loki 2.9. :tada:

Notable changes:

• Query Language Improvements: Several improvements to the query language that speed up line parsing and regex matching.
• Remote rule evaluation: Rule evaluation can now be handled by queriers to improve speed.
• Multi-store Index support: Loki now supports reading/writing indexes to multiple object stores which enables the use of different storage buckets across periods for storing index.
• New volume and volume_range endpoints: Two new endoints, index/volume and index/volume_range, have been added to Loki. They return aggregate volume information from the TSDB index for all streams matching a provided stream selector.
• New Storage Client: Add support for IBM cloud object storage as storage client.
• Block queries by hash: Queries can now be blocked by a query hash.
• logfmt stage improvements: logfmt parser now performs non-strict parsing by default which helps scan semi-structured log lines

For a full list of all changes please look at the CHANGELOG.
