Update gatewayd appVersion to v0.9.7 and refactor configuration for multi-proxy support (#15)

- Bump `appVersion` to v0.9.7 in `Chart.yaml`.
- Refactor gatewayd configuration to support multi-proxy setup:
  - Introduce separate `writes` configuration under `clients`, `pools`, and `proxies`.
  - Enable load balancing strategies for multiple proxies, including `ROUND_ROBIN` and `WEIGHTED_ROUND_ROBIN`.
- Enable `gatewaydConfig` and `gatewaydPluginsConfig`.
- Update `ConfigMap` template to align with the new multi-proxy configuration.
