Fix small bugs for release to pypi.
Small documentation fix.
Deprecated the derived MySQL metrics because they don't
accurately report information.
Update MySQL monitor documentation to reflect that dashboard is not yet ready
Merge branch 'master' of https://github.com/scalyr/scalyr-agent-2
Fix slight bug in how we read the change log that was preventing
us from having more than one release's notes in CHANGELOG.md.

Essentially, we were only looking to see if the next line belonged
to the format for the previous level instead of all the previous
levels.
Add missing comma to config file.  Scalyr's parser forgives this
but still better to have it.
Prepare change log for next release.
Updated notes for future release.
Merge branch 'master' of https://github.com/scalyr/scalyr-agent-2
Made base class PlatformController to abstract out platform-specific
details such as default paths and how to start the scalyr agent as
a service in the background.  This is being done to support the
Windows port.

Updated all affect classes and removed the platform stuff out of
the Configuration class.
Fixed import ordering issue.
Merge pull request #1 from scalyr/czerwin-platform-refactoring

Refactoring of platform-specific code
Fix bug that wasn't properly detecting if the install package
was installed through the tarball method.
Add back in comma previously removed because it unnecessarly
causes the Debian update process to warn users that there is
a new version of the config.
Merge pull request #2 from scalyr/czerwin-tarball-bugfix

Fix bug in tarball upgrade and rollback small change in config.
Refactored platforms a little more to better abstract
platform-specific monitors.
Merge pull request #3 from scalyr/czerwin-platform-modules

Refactored platforms a little more to better abstract
Added new primitives to allow for defining monitor configuration
and metric information.  For now, the metric information is
not used anywhere.
Refactored the monitor metric and option documentation features
to move the load monitor logic into the ScalyrMonitor module.

Added experimental print_monitor_doc.py script to print out the
auto-doc for a monitor, though it is still a work in progress.
