improves chainsaw single-tenancy test times by running in parallel

[ChrisJBurns]

The e2e test suite for chainsaw/operator currently takes too long to complete. This PR speeds up the single-tenancy tests by running them in parallel (initially set to 10). It does so by introducing Chainsaw bindings and templating to parameterize resources, ensuring each test run uses uniquely named objects to avoid conflicts.

Note, if you see things like (join('-', ['mcp', $testPrefix, 'proxy-lb'])), this is jmespath and how Chainsaw templates things, its not great to look at, but it works and is relatively intuitive to understand.
