Increase ip2me CIR/CBR for faster in-band file transfers (sonic-net#1000

)

Increase incoming packet rate on in-band interfaces to support faster
download of large files. SONiC firmware image download over in-band can
take a lot of time if the incoming packet rate is limited to 600pps. This,
change increases it to 6000pps. Especially when used by Zero Touch Provisioning
or by sonic_installer for firmware upgrade over in-band interfaces.
