Test errors coming from configuration

[ncherel]

• Flintrock version: 9.0.0 dev
• Python version: 3.5.2

When testing some errors can be encountered and are only related to AWS / conftest.
Two examples:

• if you include a bid price, tests with t2 instances will fail as t2 instances can't be Spot Instances
• in us-east-2, m3.medium is not an available instance

I would suggest to either change the values or warn users in the README of the test page.

Does this happen simply by running pytest, or did you edit the config somehow?

Interesting. Perhaps we should switch to m4.large.

Yes it was just by running pytest.
