Add db attributes to span data for Java backend spans

[romtsn]

Description

Follow-up from #2893

We're going to matching the otel db conventions. Either one of server.address or server.socket.address is required. If server.address is set, then server.port should be set. If server.port is different than server.socket.port, than server.socket.port should also be set. In addition, db.name should be set if possible. db.system should match the list in OpenTelemetry's well known conventions.

Attribute	Type	Description	Examples	Requirement Level
server.address	string	Name of the database host.	example.com	Conditionally Required: See alternative attributes below.
server.port	int	Logical server port number	80; 8080; 443	Conditionally Required: [1]
server.socket.address	string	Physical server IP address or Unix socket address.	10.5.3.2	See below
server.socket.port	int	Physical server port.	16456	Recommended: If different than server.port.

These values should be set on span.data.

@AbhiPrasad are any of these remaining attributes required soon / is there any date you'd like to have them by? Otherwise I'll just put this in the backlog to do at some point but without urgency.

No urgency on these, they can be backlogged for now.
