Application CR values parsing doesn't respect flattened args

[derrickburns]

I have a values.yaml file that has flattened keys like this:

  tsm.controlapp.log.level: warn

When argo parses them it does not reflect that the keys are flattened. Instead, it unflattens them.

The problem comes in when I overwrite a value. Then argo writes out the new value as a hierarchy:

tsm:
   controllapp:
     log:
       level: info

This introduces a problem for Java where the values are intended to be Java properties.

Instead, the argo UI should respect the flattened nature. If a key is given as flattened in the input, then it should be represented as flattened in the output.
