Integration tests are broken

[krinart]

First of all integration tests are not running as part of pr workflow.

They seem to have been removed in this PR #150

There are also couple of issues when running integration tests:

1. Compilation error

error[E0599]: no method named encode_to_vec found for struct arrow_flight::sql::Any in the current scope
   --> core/tests/flight/mod.rs:168:67
    |
168 |     let ticket_payload = TicketStatementQuery::default().as_any().encode_to_vec();

This can be fixed by this change:

-    let ticket_payload = TicketStatementQuery::default().as_any().encode_to_vec();
+    let ticket_payload = TicketStatementQuery::default().as_any().value.encode_to_vec();

2. The ports are not properly configured during container initialization which makes containers inaccessible. This can be fixed in core/tests/docker/mod.rs:

-                    host_port: Some(format!("{host_port}/tcp")),
+                    host_port: Some(format!("{host_port}")),

After these two fixes there's a single failure:

failures:
    flight::test_flight_sql_data_source

Which happens to be the same test the first issue was in.

Suggested changes:

1. Apply two mentioned fixes
2. Fix failing flight::test_flight_sql_data_source test
3. Make sure integration tests are running as part of pr workflow
