remove cassandra from the shiv package

so we can use the scylla-python3 driver version
the only problem now, we depend on new dbuild version
for using newer version of scylla-driver with cqlsh.

it's really slow down the ability to update new feature
that depends on new driver chanages (not too many of those)
