The API and OSC client allow to create records containing an IPv4 address with octal integer part, like 10.11.12.01.

However eventlet doesn't allow addresses with leading zeroes, causing this and all subsequent zone updates to fail in mdns:

This situation continues until the "broken" recordset is deleted.
OK - confirmed that both dnspython and eventlet explicitly block leading zeros on octets.
I think this needs to be a 2 part fix:
- one commit to update the designate objects validation to catch the leading zeros (no backport)
- one commit that does one or both of:
- Strips out leading zeros in mdns before passing to dnspython
- Fixes all records in the DB to remove the leading zeros. (probably an extra designate-manage subcommand)
I am going to set this public, as it only affects the project that creates the record, and they have a way to fix it without admin intervention.
