[bgpcfgd]: Change prefix-list generation for "Allow prefix" feature (#5639)

Browse Source 
**- Why I did it**
I was asked to change "Allow list" prefix-list generation rule.
Previously we generated the rules using following method:
``` 
For each {prefix}/{masklen} we would generate the prefix-rule
permit {prefix}/{masklen} ge {masklen}+1
Example:
Prefix 1.2.3.4/24 would have following prefix-list entry generated
permit 1.2.3.4/24 ge 23
```
But we discovered the old rule doesn't work for all cases we have.

So we introduced the new rule:
```
For ipv4 entry,  
For mask  < 32 , we will add ‘le 32’ to cover all  prefix masks to be sent by T0  
For mask =32 , we will not add any ‘le mask’ 
For ipv6 entry, we will add le 128 to cover all the prefix mask to be sent by T0  
For mask < 128 , we will add ‘le 128’ to cover all prefix masks to be sent by T0 
For mask = 128 , we will not add any ‘le mask’ 
```    

**- How I did it**
I change prefix-list entry generation function. Also I introduced a test for the changed function.

**- How to verify it**
1. Build an image and put it on your dut.

2. Create a file test_schema.conf with the test configuration
```
{
    "BGP_ALLOWED_PREFIXES": {
        "DEPLOYMENT_ID|0|1010:1010": {
            "prefixes_v4": [
                "10.20.0.0/16",
                "10.50.1.0/29"
            ],
            "prefixes_v6": [
                "fc01:10::/64",
                "fc02:20::/64"
            ]
        },
        "DEPLOYMENT_ID|0": {
            "prefixes_v4": [
                "10.20.0.0/16",
                "10.50.1.0/29"
            ],
            "prefixes_v6": [
                "fc01:10::/64",
                "fc02:20::/64"
            ]
        }
    }
}
```

3. Apply the configuration by command 
```
sonic-cfggen -j test_schema.conf --write-to-db
```

4. Check that your bgp configuration has following prefix-list entries:
```
admin@str-s6100-acs-1:~$ show runningconfiguration bgp | grep PL_ALLOW
