Kubernetes included with Docker 18.09 sets the kubectl-section to always be enabled

[MindTooth]

Bug Report

Current Behavior
With the recently released Docker 18.09 (Version 2.0.0.0-mac78), I experience that the Kubernetes section is always enabled. The reason for that is Kubernetes is now included with Docker, and the kubectl command is therefore always present. The current check is only wether if the command is present or not.

Expected Behavior
The prompt added with #76 should only be visible when needed. Inside a config folder (Dockerfile, etc. Don't know how Kube works.)

Environment

• Spacefish version: [the output of echo $SPACEFISH_VERSION]
  1.9
• Fish version: [the output of fish --version]
  fish, version 2.7.1-1181-g18a163dc
• Fish plugin manager: [e.g. oh-my-fish, fisher, fin]
  fundle
• Terminal emulator: [e.g. iTerm, Hyper, Terminator]
  kitty
• Operating system: [e.g. OSX 10.13.4, Windows 10]
  macOS Mojave

Possible Solution

Only load the section when needed.

It looks to me like this same issue would occur on spaceship with the latest version of Docker.
I think it would be best if we let them address it first.

Upon further investigation, it looks like this same issue doesn't occur on Spaceship ZSH 3.8.1 (latest right now). I'll see if I can find the cause of the problem. 🕵️

Looks I missed a bit of logic when reading over the spaceship implementation. 😅
Should be quickly fixed with the upcoming PR.

Sorry for the wait!
