[zalbiraw]

Description

Add ability to turn on OPA rules from the chart directly.

Related Issue

Motivation and Context

Issues with OPA and bootstrapping uncovered this. Default values can help direct the consumer to use the correct config rather than enabling things through extraEnvs

Test Coverage For This Change

Simply run a bootstrap with OPA enabled. if dashboard.opa.allowAdminPasswordReset is set to true the bootstrap will succeed if not it will fail with an error

You do not have permission to reset the password for other users. As an admin user, this permission can be modified using OPA rules.
