azure: identify platform by well known value in chassis asset tag.
Azure sets a known chassis asset tag to 7783-7084-3265-9085-8269-3286-77.
We can inspect this in both ds-identify and DataSource.get_data to
determine whether we are on Azure.
Added unit tests to cover these changes
and some minor tweaks to Exception error message content to give more
context on malformed or missing ovf-env.xml files.
