Giedrius Statkevičius 92218ecb9b promtool: add --ignore-unknown-fields 
Add --ignore-unknown-fields that ignores unknown fields in rule group
files. There are lots of tools in the ecosystem that "like" to extend
the rule group file structure but they are currently unreadable by
promtool if there's anything extra. The purpose of this flag is so that
we could use the "vanilla" promtool instead of rolling our own.

Some examples of tools/code:

--version Show application version.
--experimental Enable experimental commands.
--enable-feature ... Comma separated feature names to enable. Currently unused.

Commands

Command Description
help Show help.
check Check the resources for validity.
query Run query against a Prometheus server.
debug Fetch debug information.
push Push to a Prometheus server.
test Unit testing.
tsdb Run tsdb commands.
promql PromQL formatting and editing. Requires the --experimental flag.

promtool help

Show help.

Arguments

Argument Description
command Show help on command.

Check the resources for validity.

Flags

Flag Description Default
--query.lookback-delta The server's maximum query lookback duration. 5m
--extended Print extended information related to the cardinality of the metrics.
