Allow dbt-athena to grant permissions via lakeformation named resource method

[nicor88]

Context

We want to leverage dbt-athena to don't only overwrite tags, but at time, also grant permissions to specific IAM principal.

The challange when using https://docs.aws.amazon.com/lake-formation/latest/dg/tut-named-resource-method.html is that grant can be lost when a table is dropped and re-created, and that's the case with dbt when running table materialization, or full-refresh incremental models

Requirements

• extend LfGrantsConfig to support ResourcePermissionsConfig
• resource_permissions can follow this

resource_permissions:
   - principal_arn: xxxx
     permissions: 
       - select
       - describe
     grantable_permissions:
       - select
       - describe
  - principal_arn: zzz
     permissions: 
       - select
       - describe

• unit tests are provided
