Petro Bratash 4031791b4e [lldp]: Add verification IPv4 address on LLDP conf Jinja2 Template (#5699)
Fix #5812

LLDP conf Jinja2 Template does not verify IPv4 address and can use IPv6 version. This issue does not effect control LLDP daemon. Issue can be reproduced via `test_snmp_lldp` test. LLDP conf Jinja2 Template selects first item from the list of mgmt interfaces.

TESTBED_1 LLDP conf

```
configure ports eth0 lldp portidsubtype local eth0
configure system ip management pattern FC00:3::32
configure system hostname dut-1
```
TESTBED_2  LLDP conf

```
configure ports eth0 lldp portidsubtype local eth0
configure system ip management pattern 10.22.24.61
configure system hostname dut-2
```
TESTBED_1  MGMT_INTERFACE

```
$ redis-cli -n 4 keys "*" | grep MGMT_INTERFACE
MGMT_INTERFACE|eth0|10.22.24.53/23
MGMT_INTERFACE|eth0|FC00:3::32/64
```
TESTBED_2  MGMT_INTERFACE

```
$ redis-cli -n 4 keys "*" | grep MGMT_INTERFACE
MGMT_INTERFACE|eth0|FC00:3::32/64
MGMT_INTERFACE|eth0|10.22.24.61/23

```
