[logfile]: Add option to specify swss rec file name (sonic-net#1546)

What I did
Add new options to specify swss rec and sairedis rec file name.
Corresponding change in sairedis sonic-net/sonic-sairedis#747

Why I did it
This option will be used in the multi asic system. The swss and sairedis record filename will be different for each asic and will be passed from the orchagent.sh
