[Feature] Support use of "tags" field for SavedQuery

[theyostalservice]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

By adding "tags" to saved queries like many other nodes, we unlock the ability to selectively execute a subset of saved queries with simple --select commands.

Originally filed as an issue in dbt-semantic-interfaces.

Describe alternatives you've considered

We considered adding these directly to exports, but since they are not currently treated as full-fledged nodes in the dbt graph, that would be much more difficult.

Who will this benefit?

This makes the experience more consistent between semantic layer resources and other resources, and it addresses direct requests from users.

Are you interested in contributing this feature?

Yes
