Benchmarking reflection API calls, via ReportAllocs()

Hi.

I have applied such a patch - and it allowed to build, test the project:

.

@ianlancetaylor proposed such a benchmarking option:

https://golang.org/pkg/testing/#B.ReportAllocs
.

I see such lines, which invoked the reflection API:
https://github.com/apache/openwhisk-cli/blob/fcac2ac4265ec3ec7f844da95e6197b45474b407/commands/util.go#L263
https://github.com/apache/openwhisk-cli/blob/e3f41f9c0a9617774f473b12d1c379557a928bb4/commands/action.go#L891
https://github.com/apache/openwhisk-cli/blob/d4307b767c69a36ee824ada959edb3454b239d1d/commands/api.go#L70
.

What is the minimal scenario, to perform a strictly bench-marking test?
