[FEATURE] Run cypress tests with security as a PR check

Is your feature request related to a problem?

During the 2.17.0 release and 2.18.0 release there were test failures observed when running the cypress tests in the FTR repo against a cluster with the security plugin installed and enabled. In order to catch issues early, its encouraged for plugin and dashboards-plugin repos to run integration/cypress tests with security.

In 2.17.0, the test failures stemmed from test cleanup issues where ISM Dashboards relied on the ability to delete the .opendistro-ism-config passing admin credentials. A fix in the FTR repo (PR) was done to use the admin certificate when making requests against that index.

In 2.18.0, there was a separate issue in this repo due to direct system index access introduced in this PR. A reviewer of that PR left a comment that direct system index access is discouraged and the contributor replied that a follow-through would happen in the subsequent release but it looks like the comment has remained unaddressed.

To catch these issues, this repo should run the cypress test contained in this repo both with security and without security.
