[JAVA] Unable to modify the host without overwriting the whole base path

[alango]

Description

The Java client base path includes the hostname (defaulting to localhost), as well as the rest of the base path defined in the yaml. The only method to set the base path overwrites everything, so I can't set the host without overwriting the rest of the basePath which I want to keep.

Swagger-codegen version

Steps to reproduce

Online editor, Java client: https://editor.swagger.io/

Produces basePath of http://petstore.swagger.io/v2 with no method available to change the petstore.swagger.io bit without also losing the v2
