[Java Spring OAS3] Minor fixes and general improvements (#11229)

* * Use Relative Imports for org.springframework.core.io.Resource
* api.mustache: Add operationId to atOperation annotation
* Overhaul atSchema annotation in model
* Add spring-stubs-oas3.yaml test config
* Optimize mustache templates
* Use Relative Imports for DateTimeFormat, Pageable and ApiIgnore

* Add spring-stubs-oas3.yaml test config

* Generate all samples

* Explain fromOperation override to support more logic-less templates.

* Support RootUriTemplateHandler from spring-boot

* Revert "Support RootUriTemplateHandler from spring-boot"

This reverts commit 1915f8b.

* Evaluate additional property useSpringfox as Boolean

* Generate all samples after merge (java-camel)

* Fix typo

* Move java-camel test deom samples.circleci.spring to samples.circleci profile.

* re-generate all samples after merge

* Generate samples and docs after merge

* Generate samples after merge conflicts resolved
