Make AzureProperties w/ shared-key creds serializable

[snazy]

As StorageSharedKeyCredential is not serializable, shared key auth doesn't work with Spark.

@snazy could you add a test please?

[simonykq]

any eta on when this would be merged?

[nastra]

it would be good to actually create an instance of AzureProperties and verify that this matches props. Additionally, you can use

iceberg/api/src/test/java/org/apache/iceberg/TestHelpers.java

Line 99 in 5ea78e3

public static <T> T roundTripSerialize(T type) throws IOException, ClassNotFoundException {

to do the roundtrip serialization

something like

AzureProperties props =
        new AzureProperties(
            ImmutableMap.<String, String>builder()
                .put(ADLS_SAS_TOKEN_PREFIX + "foo", "bar")
                .put(ADLS_CONNECTION_STRING_PREFIX + "foo", "bar")
                .put(ADLS_READ_BLOCK_SIZE, "42")
                .put(ADLS_WRITE_BLOCK_SIZE, "42")
                .put(ADLS_SHARED_KEY_ACCOUNT_NAME, "me")
                .put(ADLS_SHARED_KEY_ACCOUNT_KEY, "secret")
                .build());

    AzureProperties serdedProps = TestHelpers.roundTripSerialize(props);
    assertThat(serdedProps.adlsReadBlockSize()).isEqualTo(props.adlsReadBlockSize());
    assertThat(serdedProps.adlsWriteBlockSize()).isEqualTo(props.adlsWriteBlockSize());
    assertThat(serdedProps.adlsSasTokens()).isEqualTo(props.adlsSasTokens());
    assertThat(serdedProps.namedKeyCreds()).isEqualTo(props.namedKeyCreds());
    assertThat(serdedProps.adlsConnectionStrings()).isEqualTo(props.adlsConnectionStrings());
