Fixes #7360.

[x] I added CHANGELOG entry for this change.
[ ] Change is not relevant to the end user.

Changes

Add new flag to query-frontend command.
Set value of remote_user field from header if flag is set.
Update docs.

Verification

Build thanos binary locally.
Start Query Frontend component. Point it to an instance of Query. Pass --query-frontend.slow-query-logs-user-header=<test header> and --query-frontend.log-queries-longer-than=1s.
Send request to /api/v1/query that contains a long-running query and sets the <test header>.
