add a flag to flutter start to configure the observatory #43

Description

@abarth

From https://github.com/flutter/tools/issues/111

Two things we'd want to do:

have it start the VM with the --pause_isolates_on_start=true flag
start it up listening on a specific port
The pause isolates flag will let us set breakpoints on isolates before they start running. Otherwise we'll miss breakpoints early in the app's lifecycle.

    cc @devoncarew still needed?

    Yeah, this will let us setup breakpoints before the app starts running. It'll be important for a good UX.

    This is covered in more specifics by other issues, and is largely (completely?) implemented.
