Refactor swatch-subscription-sync Job to use curl and internal endpoint

The swatch-subscription-sync job is defined in the clowdapp.yaml file as a cronjob.

However, this job will start the Swatch Tally service using the profiles "subscription-sync" and "kafka-queue" (see here).

The relevant profile here is "subscription-sync" which will make the Tally service to act as a command line program to execute the SubscriptionSyncJob task which does:

if (!applicationProperties.isSubscriptionSyncEnabled()) {
      log.info(
          "Will not sync subscriptions for all opted-in orgs even though job was scheduled because subscriptionSyncEnabled=false.");
      return;
    }

    try {
      controller.syncAllSubscriptionsForAllOrgs();
    } catch (Exception e) {
      throw new JobFailureException("Failed to run " + this.getClass().getSimpleName(), e);
    }

The same method is invoked by calling the endpoint "/rpc/subscriptions/sync".

Acceptance Criteria:

• Modify the "sync" job in clowdapp.yaml to invoke the "/rpc/subscriptions/sync" if and only if "${SUBSCRIPTION_SYNC_ENABLED}" is true. (As an example, the "purge" job is already invoking another endpoint here).
• Delete the spring profile "subscription-sync" since it should not be used any longer (ensure "SubscriptionSyncController" is properly imported when running the swatch tally service).
• Delete SubscriptionSyncConfiguration, SubscriptionSyncJob
• Update the diagram to remove the deleted profile
