Add Tox Nexus IQ (CLM) templates for Python
Add new templates gerrit-tox-nexus-iq-clm/github-tox-nexus-iq-clm
to analyze Python package requirements. Add script
nexus-iq-python-cli.sh with correct invocation and arguments for
the latest version of the Nexus IQ scanner.
Drop broken templates g*it-python-xc-clm, unused builder
lf-infra-clm-python and shell script nexus-iq-cli.sh.
