Addresses #376
We want to be able to accept `int` type in the `properties` field of Table
and TableMetadata.
For example,
> create_table(..., properties={"write.parquet.compression-level": 42})
This PR adds a "before" field validator to `TableMetadataCommonFields` which
will transform the values of the `properties` dict to str. Note, we explicitly
disallow `None` type, since the transformation will change `None` to str
`"None"` which is unintuitive.
