PR adds test flag -network to e2e pacakge, for the selection of the desired blockchain network for running tests. It updates readme to demonstrates usage of flag.
This change moves our e2e tests into a separate package to make room for proper unit and integration tests.
This is Phase 1 described in #371.
Changes:
Makefile has separate directives to run unit/integration tests and e2e tests,
CI runs unit/integration tests first and then e2e tests,
E2e tests are in reliability order, i.e. the least reliable tests are run in the end to be sure that nothing else is broken,
Some tests are fixed or quarantined.
