The LACP rate value for devices on testbed is expected to be set to "slow". It is so on DUT, but on VMs the rate is set to "fast".

• Steps to reproduce:

1.1) SSH to PTF host.
1.2) Run tcpdump for eth3 ("tcpdump -i eth3") and verify that LACP PDUs arrive each second.

2.1) SSH to ARISTA03T2 (as "admin").
2.2) Run next commands:
- enable
- show running-config interfaces ethernet1
- show running-config interfaces ethernet2
2.3) Using output of the last command, verify that LACP rate is set to "fast".

3.1) SSH to DUT.
3.2) Type the following command:
docker exec -i teamd teamdctl Ethernet0 state
3.3) Using output of the last command, verify that "fast rate" value is set to "no". It means that LACP rate on DUT is slow (at least, teamdctl thinks so).
