Template the `yamlApplicationConfig` value

This allows yamlApplicationConfig to include references to other values.

For example, if I have a value the determines the ingress host global.ingressHost and I want to set the OAuth2 parameters in the yamlApplicationConfig I could do something like

global:
  ingressHost: mywebsite.com

yamlApplicationConfig:
  auth:
    type: OAUTH2
    oauth2:
      client:
        keycloak:
          clientId: xxx
          clientSecret: yyy
          scope: opened
          issuer-uri: "https://{{ .Values.global.ingressHost }}/auth/realms/<realm>"
          user-name-attribute: preferred_username
          client-name: keycloak
          provider: keycloak
          custom-params:
            type: oauth

By changing global.ingressHost, the configuration for kafbat UI automatically changes to fit the new issuer-uri. Without this change, I'd have to duplicate the host configuration like

global:
  ingressHost: mywebsite.com

yamlApplicationConfig:
  auth:
    type: OAUTH2
    oauth2:
      client:
        keycloak:
          clientId: xxx
          clientSecret: yyy
          scope: opened
          issuer-uri: "https://mywebsite.com/auth/realms/<realm>"
          user-name-attribute: preferred_username
          client-name: keycloak
          provider: keycloak
          custom-params:
            type: oauth

This is very helpful when kafbat UI is a subchart of another chart.

This is strictly an enhancement, there are no breaking changes.

Congratulations on the fork! Could you tell me what the policy is here regarding version bumps? Should I bump Chart.yaml to 1.1.0?
