Cleanup jenkins scripts

[torcolvin]

The motivation to do this was that SG_TEST_BUCKET_POOL is explicitly set by this script and I think we should move to having these default values determined by the code and jenkins could optionally overwrite them.

This is a low priority change to review.

This change is no-op, there are no functional changes to the script except not requiring setting SG_TEST_BUCKET_POOL_SIZE and
SG_TEST_BUCKET_POOL_DEBUG before you call this script. Note, these are always currently set by the jenkins pipelines anyway, so the values would pass through. So this is also not a functional change with the way the jenkins jobs are set up.

• Added shellcheck action because I use this locally and it helps when refactoring.
  • Excluded all non test scripts from checking, but it will
• Fixed the scripts to make shellcheck happy
  • quoting
  • switch comparison to consistent for bash, if [ "${SG_TEST_X509:-}" == "true" -a "${COUCHBASE_SERVER_PROTOCOL}" != "couchbases" ]; then to use && instead of -a
  • switch GO_TEST_FLAGS to use a bash array so that it could be correctly quoted to appease shellcheck
• add REQUIRED_VARS check in the case I have to run the script locally, so it runs faster
• Play with -x / +x so that it doesn't output all the test [ ] and is easy to read. I used the output to debug things but I think there's enough information to debug. This might just add noise.
• Remove GO_MODULES and XATTRS since GO_MODULES isn't relevant since 3.1 and XATTRS is no longer relevant as of 4.0. This script now is always sourced from the repo, so I'm not worried about changes.
• Remove unused DOCKER_CBS_ROOT_DIR since /workspace is the only volume used for cbcollects.
• Remove \t from stdbuf -oL grep -a -E '(--- (FAIL|PASS|SKIP):|github.com/couchbase/sync_gateway(/.+)?\t|TEST: |panic: )' since grep always complainted about it, and it didn't do what it said. The scripts still find the values we need for the ok or failed for finishing package.

Testing

• ran ./jenkins-integration-build.sh -m locally to simulate MasterIntegration job.
• use ./start_server.sh locally (I already use this to create testing)

Integration Tests

• GSI=true,xattrs=true https://jenkins.sgwdev.com/job/SyncGateway-Integration/3228/
