Support setting the `target` endpoint

[n1ru4l]

We introduced new endpoints for Usage reporting.

From the new documentation:

- https://app.graphql-hive.com/usage
+ https://app.graphql-hive.com/usage/<ORGANIZATION>/<PROJECT>/<TARGET>

Retrieve the target slug from the Hive Console dashboard navigation, e.g.,
the-guild/graphql-hive/production.

Using this slug the endpoint would be
https://app.graphql-hive.com/usage/the-guild/graphql-hive/production.

Alternatively, you can also use the target's UUID instead of the slug.

- https://app.graphql-hive.com/usage
+ https://app.graphql-hive.com/usage/<TARGET_UUID>
