(DI-2108) Collector for RFC ping tests

The collector for RFC ping tests is named: /DVD/MON_CL_COL_RFC

It collects KPIs about RFC ping tests. The KPIs are defined via KPI definition and input table /DVD/MON_RFC_I1 with the following fields:

System ID	System ID
RFC destination	Logical Destination
Connection test	Should be a test connection?
Authorization test	Should be test authorization?
Ping test	Should be a test server ping?
Change by user	Last change by user [automatically filled]
Change date	Last change date [automatically filled]
Created_by	Created By User [automatically filled]
Created_at	Created At [automatically filled]

All three test groups (Connection, Authorization, Ping) make sense only when set for ABAP (3) and Internal (I) Connections. For TCP/IP (T) and HTTP Connections (G/H), the collector executes only the Connection test (Authorization and Ping tests are automatically excluded also when set in Input table).

Other RFC connection types are not supported.

Some KPIs are provided in standard delivery with the collector as examples:

KPI name	Description	Unit
RFC_IN_AUTHERR	Number of failed RFC tests - RFC check with authorization	Count
RFC_IN_CON_ERR	Number of failed RFC tests - RFC check without authorization	Count
RFC_IN_PINGERR	Number of failed RFC tests - ping server IP	Count

NOTE: All standard RFC ping test KPIs have prefix RFC_IN_*
