Add trigger-rules support

I don't have developer access so I am opening up a ticket to add support of authservice trigger rules configuration. The option is not within the config.json in the secret here: https://repo1.dso.mil/big-bang/product/packages/authservice/-/blob/main/chart/templates/secret.yaml#L15

Required additions for support:

chart/templates/secret.yaml after line 14:

      {{- if .Values.triggerRules }}
      "trigger_rules": {{ toJson .Values.triggerRules }},
      {{- end }}

Values.yaml addition:

# -- Values to bypass OIDC chains in favor of using istio authorizationpolicies.security.istio.io 
# and requestauthentications.security.istio.io for certain endpoints.
triggerRules: []
# - excluded_paths:
#     - exact: /api/healthcheck
#   included_paths:
#     - prefix: /
# See reference: https://github.com/istio-ecosystem/authservice/blob/master/docs/README.md

I would be happy to contribute with merge requests if someone will give me developer access. Thanks!
