update_engine: Support milestones to EOL from Omaha
Initiative to show EOL message on Chrome OS devices require that
update_engine parses the fields within Omaha response that pertain to the
new milestones to EOL field. The Omaha response will include a new
field called "milestones_to_eol" which will be an integer value
string.
The job of update_engine when it comes to milestones to EOL from Omaha
is to merely forward. No checks and no modifications of fields are
done within update_engine besides being able to convert the milestones
to EOL from a string to integer.
