[BP 7.1.2 MB-51778] - Log a system event when an eventing function is auto undeployed due to RBAC changes

Description

It is very important to log 1) a system event item 2) an eventing.log system log message and 3) an Application log message - when an eventing function is auto undeployed due to RBAC authorization change (deletion of either a needed resource, role or a user).

Determining why an Eventing function was undeployed if it is critical is important we want to unambiguously identify a customer error v. a system error.

Of lesser importance is when we receive Application messages like:

2022-04-08T13:35:03.426-07:00 [INFO] {"exception":"{\n \"message\": {\n \"code\": 16,\n \"desc\": \"LCB_ERR_AUTHENTICATION_FAILURE (206): Authentication error\",\n \"name\": \"LCB_ERR_AUTHENTICATION_FAILURE\"\n },\n \"stack\": \"Error\\n at OnUpdate (test26.js:5:22)\"\n}","file":"test26.js","line":4,"srcLine":"dst_col[meta.id] = doc;","stack":"Error\n at OnUpdate (test26.js:5:22)"} 2022-04-08T13:34:57.957-07:00 [INFO] {"count":3,"exception":"{\n \"message\": {\n \"code\": 16,\n \"desc\": \"LCB_ERR_AUTHENTICATION_FAILURE (206): Authentication error\",\n \"name\": \"LCB_ERR_AUTHENTICATION_FAILURE\"\n },\n \"stack\": \"Error\\n at OnUpdate (test26.js:5:22)\"\n}","file":"test26.js","line":4,"since":"2022-04-08T13:34:23","srcLine":"dst_col[meta.id] = doc;","stack":"Error\n at OnUpdate (test26.js:5:22)"}

in which we could expedite the 1 minute RBAC check due to seeing LCB_ERR_AUTHENTICATION_FAILURE in the Application log and undeploy the non-authorized function sooner. 

Note when we don't have proper RBAC the Evening system almost stalls but does make some slow progress pegging the "failure" counts in the UI.
