SNOW-1348115: Add support for column tags

[ogr003]

Is your feature request related to a problem? Please describe.

Snowflake tables support tags, but columns do not. This stops us from managing all tags within Terraform.

Describe the solution you'd like

The ability to implement tags for columns in the same way as for tables:

resource "snowflake_tag" "test_tag" {
  database       = "TEST_DB"
  schema         = "TEST_SCHEMA"
  name           = "TEST_TAG"
  allowed_values = ["TABLE", "COLUMN"]
}

resource "snowflake_table" "test_table" {
  database = snowflake_schema.schema.database
  schema   = snowflake_schema.schema.name
  name     = "TEST_TABLE"

  tag {
    name     = snowflake_tag.test_tag.name
    database = snowflake_tag.test_tag.database
    schema   = snowflake_tag.test_tag.schema
    value    = "TABLE"
  }

  column {
    name     = "data"
    type     = "text"
    nullable = false

    tag {
      name     = snowflake_tag.test_tag.name
      database = snowflake_tag.test_tag.database
      schema   = snowflake_tag.test_tag.schema
      value    = "COLUMN"
    }
  }
}

Sure, we do need this feature in our provider. I'll start working on this feature request.

Hi @ogr003 👋

We've just released v0.100.0 (release, migration guide) in which we reworked tag associations. Tags can be assigned to columns in the tag_association resource.
Please upgrade to this version and let us know if you have any issues.

closing this out as it should be fixed now as my colleague mentioned. Do let us know if you still see issues with v1.
