Move all actuator beans under `/application`

[philwebb]

The current situation of many top-level actuator URLs makes many things hard (security being the most obvious). It would be better to move them all under a single location, e.g:

• /application/health
• /application/metrics
• /application/env
• /application/beans

etc.

Don't we have /actuator right now in some cases already? I am not against /application (it sounds better actually).

[bclozel]

Should we prefix to avoid path collisions with the actual application, like /_application? Or maybe providing a property to customize that is enough.

[philwebb]

@snicoll We do currently have /actuator but I would like to change that to /application.

@bclozel We'll need a property to configure it. It might clash, but probably no more likely than the current state of affairs (/env, /health etc).

Is another property really necessary?
Shouldn't changing the default value of management.context-path handle it?

I didn't say it should be a new one :) Hopefully we can use management.context-path
