test(e2e): parallelize e2e tests

[p0mvn]

Background

Currently, e2e tests run in sequence but they don't have to be.

Suggested Design

Implement this into the e2e test suite: cosmos/cosmos-sdk#12332 so that we can run tests in-parallel safely

Ensure that #2569 is complete first

• Having the tests depend on each other does not allow running them in-parallel.

Make e2e tests run in parallel.

Acceptance Criteria

• switch to gotest.tools in e2e test suite
• ensure all tests can run in-parallel
• reconfigure the e2e test suite to execute all tests in-parallel
