feat: part 2 of TLS configs: disabling insecure

[fkywong]

Summary

A continuation of Altinity#121 (when that PR merges, the base of this PR will be updated to point back to upstream).

Most of the description and overarching intent is captured in that PR.

Changes

1. Introduce the option to set insecure: no on the cluster per the docs.
2. Updates the TLS smoke test fixture.

Limitations

1. This PR does not enable support for client TLS nor mutual TLS (mTLS).

Tests

All existing and new test features & scenarios pass locally:
