Proxy support is not cascaded into the trustee deployment

[lmilleri]

Describe the bug

Trustee Operator should inspect its environment for the standard proxy variables (HTTPS_PROXY, HTTP_PROXY, and NO_PROXY) and pass the values to trustee container(s).
The trustee-operator-controller-manager deployment is getting the proxy settings properly (when cluster-wide proxy settings are present), but the trustee-deployment is not.

How to reproduce

This bug has been reproduced in Openshift.
Steps:

1. Configure the cluster-wide proxy (e.g. https://docs.openshift.com/container-platform/4.17/networking/enable-cluster-wide-proxy.html)
2. Deploy the trustee operator

Issue: the linux standard PROXY env variables are not set in the trustee-deployment
