fix/feat: add duplicate envs without instance suffix

[kate-goldenring]

Adds Configuration broker properties without instance ID

fixes #708

Say a configuration has the following brokerProperties:

  brokerProperties:
    RESOLUTION_WIDTH: "800"
    RESOLUTION_HEIGHT: "600"

Now, the following broker envs are mounted:

RESOLUTION_WIDTH_D46B65="800"
RESOLUTION_HEIGHT_D46B65="600"
RESOLUTION_WIDTH="800"
RESOLUTION_HEIGHT="600"

Ideally, the suffixed envs would not be added (as was the case in the previous release) but to avoid doing so would require the agent to make additional K8s API calls to get the configuration for an configuration-level device plugin which is created by reconciling new instance objects.

Adds duplicate env without instance ID attached

closes #704
Example broker envs for debug echo deployment with these resource requests:
Resource requests:

          requests:
            akri.sh/akri-debug-echo-foo-ab76e6: "1"
            akri.sh/akri-debug-echo-foo-d46b65: "1"

These are the envs mounted in the broker:

DEBUG_ECHO_DESCRIPTION_D46B65=bar0
DEBUG_ECHO_DESCRIPTION_AB76E6=bar1
DEBUG_ECHO_DESCRIPTION=bar1

In this scenario, we discourage people from using DEBUG_ECHO_DESCRIPTION because it is non-deterministic. If one resource request for a Discovery Handler was issued, then DEBUG_ECHO_DESCRIPTION could be consistently used.
