Athena Create Table

* **I'm submitting a ...**
- [ ] :beetle: bug report
- [X] :rocket: feature request
- [ ] :books: construct library gap
- [ ] :phone: security issue or vulnerability => Please see [policy](https://github.com/aws/aws-cdk/security/policy)
- [ ] :question: support request => Please see note at the top of this template.

* **What is the current behavior?**
Athena Cfn and SDKs don't expose a friendly way to create tables

* **What is the expected behavior (or behavior of feature suggested)?**
I'd propose a construct that takes
* bucket name
* path
* columns: list of tuples (name, type)
* data format (probably best as an enum)
* partitions (subset of columns)

Then uses the AWS SDK Custom Resource on the Athena SDK to execute
```
querystring = """
CREATE EXTERNAL TABLE IF NOT EXISTS mydb.table_name (
`columns[0][0]` columns[0][1],
`columns[1][0]` columns[1][1]
etc...
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES (
{data_format}
) LOCATION 's3://{bucket_name}/{path}'
TBLPROPERTIES ('has_encrypted_data'='false');
"""
response = client.start_query_execution(
QueryString=querystring,
ClientRequestToken='string',
QueryExecutionContext={
'Database': 'string'
},
ResultConfiguration={
'OutputLocation': 'string',
'EncryptionConfiguration': {
'EncryptionOption': 'SSE_S3'|'SSE_KMS'|'CSE_KMS',
'KmsKey': 'string'
}
},
WorkGroup='string'
)
```

* **What is the motivation / use case for changing the behavior or adding this feature?**
Athena is the goddess of wisdom and civilization, how can we be a civilized developer tool if we don't support her?

* **Please tell us about your environment:**
All of them

* **Other information**

Start by reviewing the Athena Cfn resources and the AWS SDK Custom Resource entry point, then inspect how Athena's start_query_execution API accepts database, result, workgroup, location, columns, formats, and partitions. Done means a documented construct can create the requested external table with those inputs and has coverage for the generated query and execution configuration.
