This commit allows the kind cluster configuration to be parameterized at
call time. This enables the test suite to build multiple clusters with
different configurations, e.g. different CIDRs, different numbers of
nodes, etc.

Currently, each test suite spins up its own kind cluster, which results
in longer e2e test times as each test suite needs to wait for the
cluster to be ready and for images to download. This commit creates two
new virtual test suites that are run before and after the actual e2e
tests and are responsible for creating and destroying a kind cluster
respectively. Any test suite that needs a fresh cluster can still spin
up its own using the `create_cluster` helper in the lib.sh file.
