Nadav Har'El 77bd4afda7 test/alternator: avoid client-side validation
Ever since we started testing Alternator with tests written in Python
and using Amazon's "boto3" library, one limitation kept annoying us:

Boto3 verifies the validity of the request parameters before passing
them on to the server. It verifies that mandatory parameters are not
missing, that parameters have the right types, and sometimes even the
right ranges - all in the library before ever sending the request.
This meant that in many cases, we couldn't get good test coverage for
Alternator's server-side handling of *wrong* parameters.

As it turns out, it is trivial to tell boto3 to *not* do its client-side
request validation, with the `parameter_validation=False` config flag.
We just never noticed that such a flag existed :-)

So this patch adds this flag. It then fixes a few tests which expected
ParameterValidationError - this error is the client-side validation
failure, but should now be replaced by checking the server-side error.

The patch also adds a couple of invalid parameter checks that we
couldn't do before because of boto3's eagerness to check them on the
client side. We can add a lot more of these error tests in the future,
now that we got rid of client-side validation.
