bump(github.com/emicklei/go-restful): 692a50017a7049b26cf7ea4ccfc0d8c773...

The existing level of go-restful has a race condition when compiling path expressions, see https://github.com/emicklei/go-restful/pull/168.  The issue was fixed by this commit in go-restul: https://github.com/emicklei/go-restful/commit/692a50017a7049b26cf7ea4ccfc0d8c77369a793.  Now the paths are compiled when they are added instead of attempting to lazily compile them.
