[FEATURE]: replacing image when sync

[to266]

Feature Request

Background / Motivation

Trying to use the sync for a helm / kubernetes deployment with compiled languages

What should the user be able to do?

Have the ability to optionally replace the image of a helm/kubernetes deployment when sync

Why do they want to do this? What problem does it solve?

With compiled languages, the image that actually runs normally does not have anything required to compile the said binary, and thus the sync mode is rendered useless. If the image could be placed with something that includes the things required to compile.

Suggested Implementation(s)

Just adding the ability to replace the image should be fine
