/flags does not reflect log.level flag

[cburroughs]

What did you do?

• set -log.level=error or -log.level=debug
• went to /flags

What did you expect to see?

log.level on /flags to have the value I set.

What did you see instead? Under which circumstances?

log.level on /flags always shows "info"

It is unclear to me if this is purely a reporting issue, or if the log level is not being used correctly. When I set the log level to error I see no INFO messages on stderr (as expected), but if I set it to debug the only additional message I see is DEBU[0011] Target manager stopped source=targetmanager.go:89 on shutdown.
