Remove BBTests Resource Limits Override

Feature Request

Why

We currently override the default gluon cypress limits for bbtest. Gluon defaults to 2/2Gi . We override with:

    resources:
      requests:
        cpu: "2"
        memory: "1500M"
      limits:
        cpu: "2"
        memory: "1500M"

We've been getting OOM messages in CI runs with Mattermost. Looking at the memory usage, we boarding right there around 1500M. Bumping the limits to 2/2Gi fixes the issue. Since this is also the default for gluon, let's just remove our overrides.

Proposed Solution

• Remove our bbtests resources overrides to use the gluon defaults
• Remove the override fix that was made to umbrella's test-values.yaml to put the values back to 2/2Gi.
• Verify the default gluon values of 2/2Gi are working and the pipelines pass in the package and umbrella pipeline
