* Create windows installer.

The installer will install everything
under C:\netdata by default.

It will:
  - Install msys2 at C:\netdata
  - Install netdata dependencies with pacman
  - Install the agent itself under C:\netdata\opt

You can start the agent by running an MSYS
shell with C:\netdata\msys2_shell.cmd and
then start the agent normally with:

/opt/netdata/usr/sbin/netdata -D

There are a more couple things to work on:

  - Verify publisher.
  - Install all deps not just libuv & protobuf.
  - Figure out how we want to auto-start the agent as a service.
  - Check how to uninstall things.

* fixed typo

* code cleanup

* Create uninstaller
