Remove extra labels for fluentbit log shipping

General MR

Summary

• v3 of loki added a label limit. ever since then, fluentbit (and promtail) have been dropping certain labels to comply with the limit.
• added more labels to filter out in a lua function built into fluentbit's config map. we also hadn't realized we needed to escape - characters in those labels, so those are fixed now
• this drops enough labels such that fluentbit's error threshold is no longer reached

For Issue

Closes big-bang/product/packages/fluentbit#140 (closed)
