Send notification to dappmanager afer 5 retries

[pablomendezroyo]

Sending the notification to the dappmanager of the consensus client not being available may be too alarmistic because the consensus client may be starting or updating. Instead create a counter (either env or file) that:

• If consensus client is not available count +1
• If counter is 5 send notification to dappmanager and clean the counter
• If consensus client is reachable, clean the counter
