OpenAPI DSL does not support root security declarations

[anthony-legay]

It seems the OpenAPI DSL does not support declarations of security at root level like the specification offers it.
(see documentation here )

I made a PR by adding a SecurityDsl to merge declarations on root level and operation level: #101

What do you think about this ?
