Drop lower-constraints.txt and its testing

As discussed in TC PTG[1] and TC resolution[2], we are
dropping the lower-constraints.txt file and its testing.
We will keep lower bounds in the requirements.txt file but
with a note that these are not tested lower bounds and we
try our best to keep them updated.

This patch also fixes a broken test by updating the maximum
payload size to match the current maximum in Barbican. [3]

This patch also skips an additional broken test.  It will be
fixed in a separate patch.
