ref: Assign server_name to the device.name attribute to avoid server.address conflicts

[alexander-alderman-webb]

Description

The server.address attribute is populated by the server_name init option, as well as in integrations (e.g., in the WSGI integration). The server_name option falls back onto socket.gethostname().

In the current order, the integration value overwrites the server_name value. This value is less useful in the Sentry monolith (and could break queries on the server_name alias as there was no conflict in the transaction world).

The conventions for device.name are more narrow than server.address and align with socket.gethostname().
