Escape commands passed to run and execute

[stnguyen90]

Each element in commands should be treated as a single argument so we should escape it as an argument to prevent anything from breakint out to execute anything else.

Need to fix tests.

The tests are probably failing because the 3rd command is being escaped:

orchestration/tests/Orchestration/Base.php

Lines 465 to 472 in 450018e

	$containerId1 = static::getOrchestration()->run(
	'containerstack/alpine-stress', // https://github.com/containerstack/alpine-stress
	'UsageStats1',
	[
	'sh',
	'-c',
	'apk update && apk add screen && tail -f /dev/null',
	],
