Csaba Ringhofer 843de44788 IMPALA-13125: Fix pairwise test vector generation ...

Replaced allpairspy with a homemade pair finder that
seems to find a somewhat less optimal (larger) covering
vector set but works reliably with filters. For details
see tests/common/test_vector.py

Also fixes a few test issues uncovered. Some fixes are
copied from https://gerrit.cloudera.org/#/c/23319/

Added the possibility of shuffling vectors to get a
different test set (env var IMPALA_TEST_VECTOR_SEED).
By default the algorithm is deterministic so the test
set won't change between runs (similarly to allpairspy).

Added a new constraint to test only a single compression
per file format in some tests to reduce the number of
new vectors.

EE + custom_cluster test count in exhaustive runs:
before patch:                   ~11000
after patch:                    ~16000
without compression constraint: ~17000
