Add Spring Security

[rwinch]

This task will add Spring Security and ensure that all of the additional Filter's (gh-3, gh-5) are added to Spring Security in the proper places. We should start by using the existing Spring Security DSL (no need to create a custom DSL at this point).

Once required filters from gh-3 and gh-5 will be finished can I take a look at this?

Thanks @pkostrzewa. The issue is yours.

As gh-3 and gh-5 were closed I can progress with this issue.

@jgrandja Could you please provide a detailed description with requirements? Similar to the one available for gh-5.

@pkostrzewa This issue would simply modify the SecurityConfig in the minimal sample by http.addFilterAfter() (or http.addFilterBefore() the ClientCredentialsAuthenticationFilter (in sample) and OAuth2TokenEndpointFilter (in core).

In addition, a test should demonstrate the client obtaining the access token via the client_credentials grant.

This is no longer needed as a result of gh-25 and commit 5927475
