* [DOCS] Fix sphinx precheck

* ignore keras warnings

* Remove more warnings

Introduce the check stage to the unittest stage for now
so we don't have to rebuild CI images.
As we make additional CPU images to make use of the sphinx,
consider move it to an earlier stage.

A number of test scripts use the '|| exit 1' idiom.  This has two
issues, first process exit codes are defined to be in the range 0-255.
Second, more importantly, the idiom is fragile because it requires
that every possible failure point be explicitly coded.  This patch
removes the idiom in favour of "set -e" as used in the docker scripts
as a more robust mechanism to ensure that script failures are always
caught and propagated by default.
