Disable Login Animation using env vars

Motivation

There is a known issue in k8s port-forward, where certain file types drop the connection (https://github.com/kubernetes/kubectl/issues/1368), This affects Console Login page as background animation is one of the affected files by this issue.

How to work

To fix this, a new environment variable must be set in Console:

CONSOLE_ANIMATED_LOGIN=off

This Variable allows to disable the animation in the login page, the default value for this is on and it can be omitted by default.
