OpenTelemetry exporter uses out-dated/wrong attribute keys

[tcnghia]

In what area(s)?

/area runtime

What version of Dapr?

All versions up to 0.11

Expected Behavior

OpenTelemetry exporter uses updated attribute keys.

Actual Behavior

We observed in dapr/docs#870 that Dapr uses attribute keys from older OpenTelemetry spec. Samples of a few mismatches:

• db.type is now db.system
• db.url is now db.connection_string
• db.instance is now db.name
• There may be more

See latest OpenTelemetry spec .

See current attribute keys in Dapr

Steps to Reproduce the Problem

Go through the documentation in dapr/docs#870 and see that the statestore calls are not showing correctly. Instead of "STATE", we see "OTHER".

Release Note

RELEASE NOTE: FIX Update OpenTelemetry attribute keys db.{type,url,instance} to the latest spec db.{system,connection_string,name}

@msfussell @yaron2 I marked this issue as P1. we should fix it to use OTEL collector.
