Corrected quirks surrounding config format

* Now pickup the correct .config based on the plugin name.
* Non-existing config levels defaults to INFO instead of DEBUG
* Minimize redundancy by promoting log level from subsection
to section name.

Config format now looks accordingly:

[FATAL]
    name = com.google.gerrit.server.change.EmailReviewComments

[WARN]
    name = org.eclipse.jetty.server.session
    name = com.google.gerrit.server.plugins
