importalias

consider import path: github.com/projectcontour/x/y/z/v*

1. the alias name should be subset of x[optional]_y[optional]_z[optional]_v* where optional means it can be present or not.
2. one of x or y or z must be present in alias name.
3. If version exists in path, must be specified.
4. words like apis should be api in import alias
