The Value#hashCode() method throwed a NullPointerException for untyped values.

The mock Spanner server did not correctly return the transaction ID when
ExecuteStreamingSql was used in combination with an update count result.

Instead of returning the transaction ID of the transaction that was
actually started, it returned the transaction ID that was set on the
request. This would be empty for requests that used a Begin transaction
selector, which again meant that it would return an empty transaction ID.

This change also returns the UPDATE_COUNT field in the result set, which
is also not returned by real Spanner.

* feat: Integration Tests setup for experimental host

* added tracking bug for invalid column allow timestamp validation

* test: disable mtls checks during tests

Disable MTLS checks during tests, as the check is otherwise executed for
every stub creation. This slows down running the tests locally to the
point that they are unusable.

This workaround should be removed once googleapis/sdk-platform-java#3911
has been fixed.

If a connection has a statement timeout and a statement is executed in a read/write
transaction, the statement timeout would be reset to the original value during each
retry, instead of being reduced after each attempt. This could cause multiple
transaction retries to make the execution of a single statement take much longer
than the configured timeout value.

chore: fix tag for isolation level sample

…68.0 (#4035)

…v3.52.2 (#4057)

Add a transaction_timeout property that sets a timeout for an entire
read/write transaction. When a transaction is started, a deadline is
calculated based on the current setting for transaction_timeout. The
deadline is applied to all statements and the commit of the transaction.
