Add package and model name in surrogate_key warning

[tayloramurphy]

Description & motivation

This adds the package and model name to the surrogate key deprecation warning.

I tested by directly editing the macro in dbt modules after running deps. Produces:

Running with dbt=0.17.1
Warning: the surrogate_key macro now takes a single list argument instead of multiple string arguments. Support for multiple string arguments will be deprecated in a future release of dbt-utils. The gitlab_snowflake.arr_changes_sfdc_account_monthly model triggered this warning.
Parsing on run start hooks...
Parsing on run end hooks...
Warning: the surrogate_key macro now takes a single list argument instead of multiple string arguments. Support for multiple string arguments will be deprecated in a future release of dbt-utils. The logging.stg_dbt_audit_log model triggered this warning.

We use the exceptions.warn macro in a few other places too, what's your appetite like to update those error messages?

LMK (no pressure), and either way I'll kick off the tests
