Spike: Investigate how log aggregation can be supplied in addition to metrics

[CarsonCook]

Is your feature request related to a problem? Please describe. As a system administrator, when using metrics for performance analysis, I may also want to analyze logs of the system.

Describe the solution you'd like A way to view aggregated logs of the APIML and its onboarded services.

[CarsonCook]

Possible features:

• ignore logs that look suspicious that we know aren't
• create atomic logging that pieces together logs from each service in one time sequential log
• use rule based analysis like I do when reading logs -> got this log message therefore this can't be a problem, or GW never sees zOSMF so increase timeout and/or check certs (this could be very brittle and hard to do well)
• certain logs trigger notification (e.g. email or pop up in metrics service)?

Metrics servis is deprecated and will not be developed.
