Find Roles for Authority using the RoleHierarchy? about spring-security

[marcusdacoregio]

Hi @nielsbasjes, thanks for the suggestion.

Yes, I think it makes sense since the RoleHierarchy is applied when hasAuthority/hasAnyAuthority is used.
Feel free to provide a PR and we can go from there.

Working on it.
In the text format you can specify

   ROLE_A > ROLE_B
   ROLE_A > ROLE_C

which gives 'A' both 'B' and 'C'

In the builder this is broken.

This example gives 'A' only 'C' (the last one)

RoleHierarchyImpl.withDefaultRolePrefix()
    .role("A").implies("B")
    .role("A").implies("C")
    .build();

Fixing this in a separate commit.
