[BUG] ApacheHttpClient5Transport requires apache commons logging dependency (but not provided if RHEC excluded)

[rursprung]

What is the bug?

if you depend on opensearch-java but exclude the opensearch-rest-client (RHEC) then it fails in the runtime with the following error:

java.lang.NoClassDefFoundError: Could not initialize class org.opensearch.client.transport.httpclient5.ApacheHttpClient5Transport

How can one reproduce the bug?

in maven:

        <dependency>
            <groupId>org.opensearch.client</groupId>
            <artifactId>opensearch-java</artifactId>
            <version>2.10.3</version>
            <exclusions>
                <exclusion>
                    <groupId>org.opensearch.client</groupId>
                    <artifactId>opensearch-rest-client</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

as a workaround the following dependency can be added:

        <dependency>
            <!-- transitive dependency needed by ApacheHttpClient5Transport -->
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.3.2</version>
        </dependency>

What is the expected behavior?

the required dependencies are provided by opensearch-java, consumers do not need to know about such internals.

What is your host/environment?

tested with opensearch-java 2.10.3.

Do you have any screenshots?
