Warn user when not specifying -m flag in start_nf.sh

[dennisafa]

Warn the user if -m isn't specified in start_nf.sh

Summary:

You can bind a core manually using -l and -m in the start_nf script. If -m isn't specified, no binding will occur. This change will let the user know that they should supply this flag if they want the binding to occur.
Usage:
Run any NF using the ./start_nf.sh NF-NAME DPDK_ARGS -- ONVM_ARGS -- NF_ARGS format
(i.e, ./start_nf.sh speed_tester -l 5 -- -m -r 3 -- -d 2 where is -l is the core # to assign, and -m is the binding flag)

I think it looks good, really just a bash nit, and Nick can dispute, but personally I like combining those conditions, as well as using built-in regex.
[[ $DPDK_ARGS =~ "-l" && ! $ONVM_ARGS =~ "-m" ]]

Lgtm, testing is on you though. I like @kevindweb nit looks elegant

Tested with CI and cloudlab, all performance looks good, as well as Pktgen, and multiple speed testers running.
