Enable bmcweb dynamic logging
Create a CLI app called "bmcweb" that can set logging levels on
"bmcwebd", the new bmcweb daemon. Create a dbus connection to set log
level using the CLI app Define the "setLogLevel" method on dbus to
control logging level in bmcwebd Add logic to move logging level from
build option to dynamic overloading
Reason: bmcweb picks up logging level as a compile flag. We want it to
be more flexible to debug errors in the field. Using the bmcweb CLI
app, we can set log levels on the bmcweb daemon during runtime.
Splitting bmcweb.
For example, to set logging level to INFO on the target:
bmcweb -l INFO
