The docs on metric labels suggests that they should probably be strings,
and all others I can find are strings, and so these ought to be also.
Otherwise, some of the exporters/processors have to handle things
specifically, and not all of these come out as nice as could be when you
`str()` them.
I've also made sure to use the `StatusCode` name, as that's the
interesting thing.
Finally, there's no need to report specifically that `error=false`, so
I've removed that tag.
Changes:
- Update dbapi instrumentation to use the SQL statement name as the span
instead of the entire SQL query.
- Renamed TracedCursor with CursorTracing. The class was not a valid
Cursor so the name was confusing.
- Updated CursorTracing's (previously TracedCursor) traced_execution
method to accept the cursor instance as the first argument. This is
required as for some dbapi implementations, we need a reference to the
cursor in order to correctly format the SQL query.
- Updated psycopg2 instrumentation to leverage dbapi's `cursor_factory`
mechanism instead of wrapping the cursor with wrapt. This results in a
simpler instrumentation without monkey patching objects at runtime and
allows psycopg2's type registration system to work. This should make it
possible to use psycopg2 instrumentation when using the JSONB feature or
with frameworks like Django.
Current instrumentation uses the entire SQL query as the operation name
which makes traces very hard to read and understand in addition to
introducing high-cardinality issues. This commit fixes the problem by
using only the SQL operation name and the DB name instead of the entire
query.
SQLAlchemy spans were missing kind field and it was being set to
internal instead of client. This commit changes sqlalchemy spans to have
kind set to "client" instead.

If a Flask request doesn't have an active span, it just means that it
was initialized via a mechanism that doesn't run `before_request`, like
`app.test_request_context` or even manually. It is okay and
instrumentation still works.
