* Address `boto` deprecation warnings
This commit eliminates the following warning:
../boto/ec2/connection.py:582:
PendingDeprecationWarning: The current get_all_instances implementation will be replaced with get_all_reservations.
`boto` isn't likely to ever make good on this warning, but doing the replacement will
declutter the `moto` test output.
* Remove `invoke_lambda` tracebacks from unit test logging
If an exception is encountered, the details are returned in the response payload.
Printing the traceback was just adding noise to the pytest output.
* Use known AMIs in unit tests
This commit eliminates the following warning in the pytest output:
`PendingDeprecationWarning: Could not find AMI with image-id:ami-123456, in the near future this will cause an error.`
Known, pre-loaded AMI image ids are used instead of random ids that don't actually
exist in the moto backend. The integrity of the tests is unaffected by this change.
A test has been added to provide explicit coverage of the PendingDeprecationWarning
raised when an invalid AMI image id is passed to moto.
When an instance is running, OpsWorks reports its status as "online"
[1], while EC2 reports it as "running". Until now, moto copied the EC2
instance's status as is. This commit introduces the converts the running
status to online when returned by OpsWorks.
