Enable functionality to use common schema in model database

[jodybuz]

A new variable has been added use_common_masking_policy_schema_only which allows for a common schema within the model database to be specified for storing masking policies.

(Similar to existing functionality which uses use_common_masking_policy_db to set a common database and schema to store masking policies.)

@jodybuz , Thank You for the PR. I will review/test and get back.

• Can you also update the README.md with the details on how to use this new feature ?
• I also see changes to "integration_tests/dbt_project.yml", was that required ?

Thanks @entechlog - I have made some updates to the README this morning. Hopefully it makes things easier to understand.

I've also removed the formatting in the "integration_tests/dbt_project.yml" file. (Sorry - these were added by my linter - so not necessary.) But I've kept in my new parameter to enable future testing - hope thats ok?

Thank You @jodybuz , I will test this and get it merged

Hi @entechlog - Sorry, but I've added one last change into this PR (hope it's not too late.) We have custom materializations in our dbt project, so I've added a parameter which allows your package to apply masking policies to these types of models. I've updated the README with instructions on how to use this feature too.

@jodybuz , Sure. Sorry I have been busy for last couple of days. I will try to take a look at them today evening

@jodybuz , The tests ran fine, so going a head and merging this now.

Thanks @entechlog and @nadesansiva - this is going to be so useful for us (and hopefully others too.)
