Increase the amount of pylint messages that cause an error by adding an exitcheck yto the yaml file

For all PRs related:
These we already check for but didn't error on

So far for only spinn_ultis the .pylintrc has been updated toremove all but a few exception listed below

https://pylint.readthedocs.io/en/latest/user_guide/messages/convention/import-outside-toplevel.html

These pylint checks are globally disabled:

https://pylint.readthedocs.io/en/latest/user_guide/messages/convention/consider-using-dict-items.html
Would require going from
for x in foo:
to
for x in foo.items()

https://pylint.readthedocs.io/en/latest/user_guide/messages/convention/missing-module-docstring.html
Requires a comment at import level.
We do the comments at class level.
