Stop sorting of termination_policies in ec2_asg (#4883)

Browse source 
The AWS API requires that any termination policy list that includes
`Default` must end with Default. The attribute sorting caused any list
of attributes to be lexically sorted, so a list like
`["OldestLaunchConfiguration", "Default"]` would be changed to
`["Default", "OldestLaunchConfiguration"]` because default is earlier
alphabetically. This caused calls to fail with BotoServerError per #4069

This commit also adds proper tracebacks to all botoservererror fail_json
calls.

Closes #4069
