[20.10] vendor: compose-on-kubernetes v0.5.0 to remove github.com/golang/glog

glog has the same issue as k8s.io/klog, and is calling `user.Current()`
inside an `init()`; see 466fbb6507

Calling `user.Current()` on Windows can result in remove connections being
made to get the user's information, which can be a heavy call. See #2420

glog was only used in a single location in compose-on-kubernetes, so we may as
well remove it.

-Leveled execution logs for Go.
-
-This is an efficient pure Go implementation of leveled logs in the
-manner of the open source C++ package
-	https://github.com/google/glog
-
-By binding methods to booleans it is possible to use the log package
-without paying the expense of evaluating the arguments to the log.
-Through the -vmodule flag, the package also provides fine-grained
-control over logging at the file level.
-
-The comment from glog.go introduces the ideas:
-
-	Package glog implements logging analogous to the Google-internal
-	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
-	Error, Fatal, plus formatting variants such as Infof. It
-	also provides V-style logging controlled by the -v and
-	-vmodule=file=2 flags.
-	
-	Basic examples:
-	
-		glog.Info("Prepare to repel boarders")
-	
-		glog.Fatalf("Initialization failed: %s", err)
-	
-	See the documentation for the V function for an explanation
-	of these examples:
-	
-		if glog.V(2) {
-			glog.Info("Starting transaction...")
-		}
-	
-		glog.V(2).Infoln("Processed", nItems, "elements")
-
-
-The repository contains an open source version of the log package
-used inside Google. The master copy of the source lives inside
-Google, not here. The code in this repo is for export only and is not itself
-under development. Feature requests will be ignored.
-
-Send bug reports to golang-nuts@googlegroups.com.
