Conditional execution

TLDR;

Opctl supports using if statements and predicates to make parts of your op run conditionally.

Example

1. Start this op:

   name: conditionalExecution
   inputs:
     shouldRunContainer:
       description: whether to run the container or not
       boolean: {}
   run:
     if:
       - eq: [true, $(shouldRunContainer)]
     container:
       cmd: [echo, 'hello!']
       image: { ref: ghcr.io/linuxcontainers/alpine }

2. When prompted, enter true or false
3. Observe you only see the container run and hello! logged when you enter true.
