[TSA]: Fix TSC. Avoid 'Not consistent' state

[pavel-shirshov]

- Why I did it
Fixes: #5957
It is addition to #5906

- How I did it
When TSC checks for route-maps, skip all route-maps which are not included V4 or V6. Check the previous PR

- How to verify it
First restart dut, then do sudo config reload -y, then TSA, then TSC. See the example below:

admin@str-s6100-acs-1:~$ uptime
 00:38:55 up 1 min,  1 user,  load average: 4.03, 1.69, 0.62
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Normal
admin@str-s6100-acs-1:~$ sudo config reload -y
