Table update seems to be unsupported

[Kwaq]

What happened?

POST to /bigquery/v2/projects/{projectId}/datasets/{datasetId}/tables/{tableId}
results in 500 Internal Server Error with message

"unexpected request path: /bigquery/v2/projects/{projectId}/datasets/{datasetId}/tables/{tableId} "

What did you expect to happen?

Table updated sucessfully.

How can we reproduce it (as minimally and precisely as possible)?

Using Java BQ API:

final TableId tableId = TableId.of("test-project", "test-dataset", "test-table");
final Table table = bigQuery.getTable(tableId);

table.toBuilder()
  .setExpirationTime(7)
  .build()
  .update();

Anything else we need to know?

No response

Dig deeper into Java API and it turns out that it overrides PATCH (which is implemented by the Emulator) with POST which is not.
The actual method is set in the X-HTTP-Method-Override header.
This works in real BigQuery but does not in the emulator.
Would it be possible to add support for X-HTTP-Method-Override header?
