* automated test for viewing traces from zipkin dashboard (expectation is that traces are seen correctly)
* fix shellcheck linting errors
* remove verification of traces and just check if zipkin dashboard is accessible through port-forward
* Modify snippet generation logic to take {{< boilerplate >}} into account
* snippets for boilerplate
* fix shellcheck (linting) issues
* snippets generated with new logic
* automated test - check if zipkin dashboard is accessible by port-forwarding (as we cannot verify screenshot and the trace is already verified in istio/istio integration test
* clean up ZIPKIN_URL comment
* Address code review comments
1. Simplify boilerplate snippet filenames (remove .md_snips)
2. Sourced filenames should be in double quote(") instead of single quote(')
* fix gencheck_istio flake
* do not generate or include boilerplate snippets if there is not {{<text>}} in them
* fix linting errors in snip.py
* fix bug - filter out boilerplates without snippets very early
* snip.py: Replace github file token with release-specific URL.
* verify.sh: Show the expected output as well as the actual output.
* snip.py: Update the githubfile regex to not include email addresses.
When generating snip scripts, pairs of "@" signs indicate a link to
GitHub repo content. However, JWT attribute values contained pairs of
email addresses such as:
`testing@secure.istio.io/testing@secure.istio.io`
which would be treated as an email address and mangled. This commit
rewrites the regex to not match on email addresses.
* Add authz-jwt user guide test.
Reverted the actual mirror test script, because mirror test seems to have some subtle failure when running with what seems to be the exact same commands via snips. Will investigate further in followup PR. Merging this one to get the generator changes.
