Parameterize end-to-end test scripts

[Yanson]

What this PR does / why we need it:

Allow GCP project/bucket to be set in environment when running end-to-end tests. This is to allow us to run the e2e tests on our CI (Cloud Build) against our own GCP resources.

Additionally, 1/ allow skipping building of jars in e2e steps as we build them in a previous step, 2/ allow suffix to be specified to find jar as we use commit has rather than SNAPSHOT, 3/ print feast logs on test failure to help diagnosis.

This PR also aligns test-end-to-end.sh and test-end-to-end-batch.sh much more closely.

Which issue(s) this PR fixes:
This does not fix anything. The motivation was to be able replicate the test failures in #431 .

Does this PR introduce a user-facing change?:

NONE

Hi @Yanson. Thanks for your PR.

I'm waiting for a gojek member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
