[PATCH 0/7] refactor kvargs test

[PATCH 0/7] refactor kvargs test

[Chengwen Feng]

When developing patchset [1], I found the kvargs test is hard to 
understand when tried to add some testcase.

So refactor kvargs by:
1. introduce UT suite framework.
2. extract big test_valid_kvargs() to five part.

And add myself for voluntary maintenance of the kvargs library.

Note: to ensure patch independenct, new API which in patchset [1]
are not included in this patchset.

[1] https://patchwork.dpdk.org/project/dpdk/cover/20231103073811.13196-1-fengchengwen@huawei.com/

Chengwen Feng (7):
  app/test: introduce UT suite framework for kvargs
  app/test: extract basic token count testcase for kvargs
  app/test: extract without keys testcase for kvargs
  app/test: extract with keys testcase for kvargs
  app/test: extract parse list value testcase for kvargs
  app/test: extract parse empty elements testcase for kvargs
  maintainers: update for kvargs library
