add more parameters to plonecli test

the more the better ;)

currently plonecli test -h shows

  -a, --all
  -t, --test TEXT
  -s, --package TEXT
  -h, --help          Show this message and exit.

while ./bin/test -h shows a whole lot more.

i'd love to see more of those features in plonecli test or a bypass to use those arguments given by ./bin/test

especially these:

--verbose, -v

--list-tests

--post-mortem, --pdb, -D

--progress, -p
--no-progress

--color, -c
--no-color, -C
--auto-color

Start by locating the implementation of the plonecli test command and compare its accepted options with the output of ./bin/test -h. Determine whether the listed options should be exposed directly or passed through, then verify that the selected arguments appear in plonecli test -h and work as expected.
