[JaxRsSpec] Add apiNameSuffix config option

[ndurette]

Description

I was trying to overwrite the Api name suffix like I was able to do with the model name.
Unfortunately it seems that this feature doesn't exist yet. I saw that it was already requested at some points (#4028), but was never implemented.

In my case, I want to generate the "apis" as kind of an interface so I would like to be able to rename it.

Swagger-codegen version

swagger-codegen 2.3.0

Swagger declaration file content or url

It would be nice to have this parameter available:

{
    "apiNameSuffix": "Suffix"
}
