Add make targets recetprotctl_install, test_skip_kube and modify test

[john-westcott-iv]

recetprotctl_install - builds and installs receptorctl into your python environment in one command
test_skuo_kube - sets SKIP_KUBE env var = 1 before running test
test - now add pwd to your path (to pickup a built but not installed receptor binary) and tells you what binary its choosing for the test:

make test
Testing with receptor binary from: /home/jowestco/GIT/github/john-westcott-iv/receptor/receptor
?   	github.com/ansible/receptor/cmd/receptor-cb	[no test files]
?   	github.com/ansible/receptor/cmd/receptor-cl	[no test files]
...

Addresses #108

I really wish we didn't merge most of this code. I would like to see everything reverted except for lines 92 and 94, but both of those lines also have issues that I've noted in-line.

[shanemcd]

The way this is written breaks the ability to override this variable via an environment variable. Let's use this stripped-down Makefile as an example:

SKIP_KUBE=0

test:
	@echo $(SKIP_KUBE)

The output is:

$ SKIP_KUBE=1 make test
0

If written it like this:

SKIP_KUBE ?= 0

test:
	@echo $(SKIP_KUBE)

It works as expected:

$ SKIP_KUBE=1 make test
1

One of the primary design aspects of Make is to augment its behavior by overriding variables. If we were to follow this pattern you've started here, things would get unwieldy rather quickly. This new target is unnecessary as you could achieve the same thing by running:

SKIP_KUBE=1 make test

[shanemcd]

This is unnecessary if you set the variable like I show in my comment above.

Another issue here is the indentation. There should be only 1 tab character here, followed by the number of spaces you would like to indent the code.

[shanemcd]

Not all environments will have which, and this hides the error so it will be hard to tell what's going on without coming to look at this code.

[shanemcd]

These targets are unnecessary so they should be removed, but in the future, stuff like this should be added under .PHONY.

[shanemcd]

Wouldn't we want to invert the precedence here to always prefer the build artifact?

[shanemcd]

The commit message also has a typo... 😓

Add make targets recetprotctl_install, test_skip_kube and modify test

Going forward we should slow down and make sure there is adequate time for feedback and discussion. I don't see anything in here that would be considered urgent.
