Brad Fitzpatrick 57dd247376 cmd/tailscaled, logpolicy, logtail: support log levels
Log levels can now be specified with "[v1] " or "[v2] " substrings
that are then stripped and filtered at the final logger. This follows
our existing "[unexpected]" etc convention and doesn't require a
wholesale reworking of our logging at the moment.

cmd/tailscaled then gets a new --verbose=N flag to take a log level
that controls what gets logged to stderr (and thus systemd, syslog,
etc). Logtail is unaffected by --verbose.

This commit doesn't add annotations to any existing log prints. That
is in the next commit.

Updates #924
Updates #282
