Proposed changes

Add workerConnections field to helm chart

Problem: workerConnections was not able to be configured by helm

Solution: I added the field to the schema.

Testing: I tested a new helm chart with workerConnections set to 2048 and saw that the NginxProxy resource had the correct value and the worker connections field appeared in the conf as well.

Please focus on (optional): If you any specific areas where you would like reviewers to focus their attention or provide
