Prometheus remote write proxy which marks timeseries with a Cortex/Mimir tenant ID based on labels.

Cortex/Mimir tenants (separate namespaces where metrics are stored to and queried from) are identified by X-Scope-OrgID HTTP header on both writes and queries.

This software solves the problem using the following logic:

• Receive Prometheus remote write
• Search each timeseries for a specific label name and extract a tenant ID from its value. If the label wasn't found then it can fall back to a configurable default ID. If none is configured then the write request will be rejected with HTTP code 400
• Optionally removes this label from the timeseries
• Groups timeseries by tenant
• Issues a number of parallel per-tenant HTTP requests to Cortex/Mimir with the relevant tenant HTTP header (X-Scope-OrgID by default)
