This is the guide about how to make goconserver as
a replacement for conserver to help slove the issues reported
for conserver, like: #4043, #3543. For openbmc, the solution of
goconserver is much light-weighted than the conserver which could
help save the system resource. In addition, sshpass is not needed
for openbmc with goconserver.
Implement: #4337
This commit add descritpion for `dbtracelevel` entry in site table
