Update Get Recordset Change Route

[Aravindh-Raju]

Currently the Get Recordset Change has a Segment which is of no use. It's not passed on to any service methods or used anywhere. We should remove that to avoid any confusion.

For eg in the below api, the segment next to recordsets is of no use. It can be anything like dummy, test or whatever and it'll still work as it is not used anywhere or provide any use:

https://localhost:9000/zones/3db0d8y4-967c-46fa-9560-560b11m5cb38/recordsets/{this can be anything. it doesn't matter}/changes/09950016-14bd-469a-bc62-9e8b0zlka69
