[FEATURE] Unity table tag support in databricks_sql_table

[donatasm]

Proposal

Similar to existing key value definitions in databricks_sql_table like options or properties proposal is to have tags attribute:

databricks_sql_table {
    name = "test_table"
    ...
    tags = {
        key1 = value1
        key2 = value2
    }
}

Implementation in resource_sql_table.go would additionally execute:

ALTER TABLE 'test_table' SET tags ('key1' = 'value1', 'key2' = 'value2')
