Gitops repo to be prefixed with a unique identifier

[prakarsh-dt]

Summary

Gitops repo to be prefixed with a unique identifier so that it doesn't overlaps with the source code repo name.

Motivation

Some users want to evaluate Devtron and don't want to create a separate github organization / gitlab group for Devtron GitOps (although this is not recommended for Production use). This creates problem if they keep their devtron app name same as the name of their source code repo.

Proposal

Add a random prefix / unique identifier before creating the Devtron GitOps repo.
