iox-sql: IPv6 address parser defect

[lmangani]

The current implementation of the iox sql dataSourceName parameter doesn't support parsing IPv6 addresses with ports.
When a domain resolving to an IPv6 address is used the function works as expected, confirming underlying IPv6 works fine.

Opening this issue to track and provide a fix.

Example

When configuring an IPv6 address

  dataSourceName: "iox://[xxxx:yyyy:1:::zzzz]:8082/company_sensors?secure=false",

"transport: Error while dialing dial tcp: address xxxx:yyyy:1:::zzzz:8082: too many colons in address"
