Added OTEL DB stats metrics, renamed trace attributes to expected OTEL names (#42097)
1. Added DB metrics via otelsql.RegisterDBStatsMetrics()
`db.sql.connection.open`
`db.sql.connection.max_open`
`db.sql.connection.wait`
`db.sql.connection.wait_duration`
`db.sql.connection.closed_max_idle`
`db.sql.connection.closed_max_idle_time`
`db.sql.latency.*`
2. renamed these metrics to signoz convention/expected names
`db.sql.connection.open` -> `db.client.connection.usage`
`db.sql.connection.max_open` -> `db.client.connection.max`
`db.sql.connection.wait` -> `db.client.connection.wait_count`
`db.sql.connection.wait_duration` -> `db.client.connection.wait_time`
`db.sql.connection.closed_max_idle` -> `db.client.connection.idle.max`
`db.sql.connection.closed_max_idle_time` ->
`db.client.connection.idle.min`
3. created custom dashboard to display these metrics, (import via json)

/>
4. Fixed metrics for service db dashboards
Signoz expects

`db.system` : Identifies the database type (e.g., postgresql, mysql,
mongodb).
`db.statement` : The actual query being executed (e.g., SELECT * FROM
users).
`db.operation` : The type of operation (e.g., SELECT, INSERT).
`service.name` : The name of the service making the call.

We needed to set the `db.system` attribute explicitly.

`db.operation` is missing because otelsql doesn't capture this by
default. Decided not to add this for now as the dashboards work without.
Can be a future enhancement.
