Improving the validation experience

[thekaveman]

Both the UX of the module itself and the errors/messages it produces.

Still WIP, pending further error output improvements.

Ok, this is pretty good for now. Example usage:

from mds.schema.validation import ProviderDataValidator

v = ProviderDataValidator(schema_type="status_changes", ref="dev")
data = {}

for error in v.validate(data):
    print(error)

Outputs:

'version' is a required property
'data' is a required property
