K9s: Templating in plugins are not working as expected

[joskfg]

Describe the bug
The args in the plugins have a templating system to allow concatenate strings with varaibles like $COL0. It doesn't work in complex strings. Check #303

To Reproduce
Steps to reproduce the behavior:

1. Go to your plugins.yaml
2. Add the next code

  suspendCronsSwitch:
    shortCut: Ctrl-S
    scopes:
    - cj
    description: Suspend
    command: kubectl
    background: true
    args:
    - patch
    - cronjobs
    - $COL0
    - -p
    - '{"spec" : {"suspend" : $COL2 }}'

1. Go to cornjob view and execute the plughin while checking with ps aux what is being launched

while true; do ps aux | grep kubectl | grep -v .svn | grep -v defunct; done

Expected behavior
$COL2 is replace with the valie True or False

Screenshots

Versions (please complete the following information):

• OS: Ubuntu
• K9s 0.12.0
• K8s v1.14.7-gke.23

Additional context
I needed that to execute a bash that switch between True and False strings. I workaround that using two plugins:

  suspendCronsSwitch:
    shortCut: Ctrl-S
    scopes:
    - cj
    description: Suspend
    command: kubectl
    background: true
    args:
    - patch
    - cronjobs
    - $COL0
    - -p
    - '{"spec" : {"suspend" : true }}'
  enableCronsSwitch:
    shortCut: Ctrl-E
    scopes:
    - cj
    description: Enable
    command: kubectl
    background: true
    args:
    - patch
    - cronjobs
    - $COL0
    - -p
    - '{"spec" : {"suspend" : false }}'
