Make health show-details and show-components technology specific

[philwebb]

Currently management.endpoint.health.show-components and management.endpoint.health.show-details aren't applied to JMX endpoints. This is a little confusing and we think it would be better to create technology specific variants:

For JMX we can have:

management.endpoint.health.jmx.show-components
management.endpoint.health.jmx.show-details

And for Web we can have:

management.endpoint.health.web.show-components
management.endpoint.health.web.show-details

Another subtle difference is that HealthProperties.Show has NEVER, WHEN_AUTHORIZED and ALWAYS. For JMX, we don't have the concept of an authorized user so we can't offer it as an option.

Once added, we can deprecate management.endpoint.health.show-components and management.endpoint.health.show-details and consider them aliases for the web version.

@philwebb this would then also apply to health groups, right?

So, this should be possible:

management.endpoint.health.group.custom.jmx.show-components
management.endpoint.health.group.custom.jmx.show-details

management.endpoint.health.group.custom.web.show-components
management.endpoint.health.group.custom.web.show-details

Thanks @jsattler for pointing that out. We have decided not to introduce the technology split as it could inflict unwanted upgrade pain for users without too much benefit. We've decided to stick with the original design where JMX users are always shown the details.
