Discover host targets manually in OEM 12c - emctl config agent addinternaltargets

In case of silent installation of OEM 12c Agent sometimes the host target monitoring is not picked up and it is not visible in OEM console as well.

When checked in the /u01/app/oracle/agent_inst/sysman/emd/targets.xml file we couldn't find information related to the host.

To fix this we need to run "emctl config agent addInternalTargets". This forces the agent to rediscover the host.
