Would making this an int (the actual log level passed) give us more flexibility?

I am in favor of a boolean rather than an integer.

For starters, I think it is simpler to just have default+all modes exposed.
Secondly I am removing the integer based LogLevel in favor of a "CaptureMode"
class in https://codereview.chromium.org/1059843002/ so using an integer is not
going to work as well following that change.

I've kept it as the boolean default-or-all choice, since that seems to fill our
immediately foreseeable needs, and exposing the whole NetLogCaptureMode logic to
the Java side seems like extra complexity.
