Do not write UVEs in the log file

[Sundaresan Rajangam]

Recently, default log level for the sandesh uve has been changed to SYS_NOTICE. log_level is set to SYS_NOTICE in conf file for all contrail services. This causes the log file for all services to be flooded with the sandesh UVE logs. Most of the stats are sent as UVEs and are periodic. Since the UVEs can be queried using analytics REST API or fetched from the service's introspect, uves should not be written in the log file.

Log UVEs only at SandeshLevel::INVALID

As part of constrained analytics we changed the default
SandeshLevel of UVEs to SYS_NOTICE from INVALID. Due to
this the log files of all daemons started getting flooded
with UVE logs since the default log_level is set to
SYS_NOTICE. To workaround this we will treat the UVE
log level as INVALID when determining whether to log.
