add 'lint-all-code' as wrapper of lint builders

OPNFV has common coding style [1]. So, all repos shall be checked by
one generic checker builder/job, eventually.

This patch adds lint wrapper builder 'lint-all-code', and also
refactors all exisiting lint and syntax check builders, following
'lint-yaml-code' builder approach, which only checks modified files.
This approach is nice as it won't require immediate fixes of violations
in whole repo code right after the lint checker job is enabled.

Note that lint jobs are still configured to run against some project
repo, in order to seperate discussion; wheter we should apply this
lint job to all OPNFV repo or not immediately.
