Adding output files deletion functionality

[unlimitedbits]

Hi,

we are considering using gomplate for rendering configurations for infrastructure rollouts (e.g. outputting terraform files).
As we want to support the full lifecycle of such components, it would also be handy if gomplate was able to just delete the output files of a templating step, especially as we are using outputMap and the actual output path for the input templates is different based on the datasources and the target folder potentially also consists of other files.

From our side two options could really help here:

• Adding a --delete option to the CLI so that gomplate is deleting the output files instead of rendering
• Adding something like a --dry-run option which prints the paths of all files which would be rendered

Would you consider adding one of those options to gomplate?
