Add Service watchers and chia-healthcheck sidecar

[Starttoaster]

Main features of this PR:

• Adds Watches to all Services to trigger a reconcile request if a custom-resource-owned Service is ever manually updated to fix Service objects owned by this operator
• Adds chia-healthcheck to the list of optional sidecar containers for seeders and full_nodes

And also:

• Slimmed down controller functions that had unused arguments and receivers. Removing them makes the functions easier to test, and easier to keep track of what the function actually does.
• Reorganizes some controller code to use a chia container builder function to have a consistent way to build the chia container and reduce code duplication and increase testability
• Reorganize some Service assembler function logic to reduce a bit of code duplication and increase testability
• Turns off zap's Development mode logger, which mostly means we won't get stack traces on warning logs (only error logs) with the production logger
• Refines documentation
