Move the default location of the log files into a configurable logs
folder and split the written logs up by UTC date to more easily allow
deleting of old logs to be performed. The log rotation is implemented
by winston-daily-rotate-file.
The old log format will automatically be migrated to the new format and
location if the target folder for the new logs don't yet exists.
Move the depenedncies needed to run the tests into test/package.json and
manage it using lerna. This should make it easier to selectively
install only what's needed to run the software.
Add winston based logger for master, slave, ctl, lib, and web_ui code.
Logging done from slaves and instances are sent to the master server and
tagged with the instance and/or slave it originated from. This allows
for example error messages to propagate back to the source that iniated
the action. The master server also stores the log to allow it to be
queried at a later point. For slaves a copy of the slave's log is also
stored locally.
Split up codebase into the packages @clsterio/lib, @clusterio/master,
@clusterio/slave, and @clusterio/ctl using lerna to manage them. This
will allow deployment to use only the parts needed reducing install
size, and better separate the code into shared library, master, slave
and control.
