Add alert for performance metrics about avni-infra

[mahalakshme]

@vinayvenu should we add newrelic alarm to identify when response time degrades? I felt the above ll suffice, Wondered, if there are too many alerts we might not monitor anything.

Works I think @mahalakshme

Vinays comment in skype: newrelic alerts might be better since they measure the true problem, irrespective of what is happening on the infra side

so @vinayvenu since not all performance degradation/overload issues in AWS can be correspondingly identified from some newrelic indicator(correct me if I am wrong), have modified the AC accordingly.

We are talking alerts, not analysis.

For alerts, newrelic is enough.

RWB Newrelic account:

• Added Average Response Time across 5 mins > 1 sec alert
• Added Storage alert > 80% for prod servers
  Will monitor how much data is additionally sent for infra monitoring and add alerting for reporting and non prod environment as well if we are not in danger of breaching the free plan limits.
