Refactor security/integration/jersey* to microprofile/security

[romain-grecourt]

The jersey support is now non public and is an implementation detail of the Helidon MicroProfile server.

security/integration/jersey is usable independently of Helidon, however it does not make sense for Helidon to provide and support standalone security for Jersey.

The module requires a server for testing, thus given that the jersey support is not public the test must use @HelidonTest.

It makes sense to refactor the Jersey security into microprofile/security to confirm the direction we are taking where the Jersey support is not available as a Nima API but rather implicitly with the Helidon MicroProfile server.

• Refactor security/integration/jersey* to microprofile/security
• Refactor examples/security/jersey to examples/microprofile/security
