Loki - v2.7.2

This is release v2.7.2 of Loki, a patch release of the v2.7 minor release.

Notable bug fixes:

• Fixed bug in validation of pattern and regexp parsers where missing or empty parameters for these parsers caused panics.
• Fixed bugs in processing delete requests with line filters:
• Whole chunks covered by delete requests with a line filter were incorrectly skipped.
• Chunks partially covered by delete requests with a line filter were not properly processed.
  The part that was not covered by the delete request was rewritten with a line filter, while the part that was covered by the delete request was completely deleted.
• Fixed bug in multi-tenant querying that caused HTTP 400 responses when multiple tenants where used in X-Scope-OrgID header like so tenant-a|tenant-b.
• Upgraded Go build version and Docker container base images to 1.19.5 to mitigate GO-2022-1144 vulnerability.
