Update testcontainers to 1.16.0.

[malcyon]

Description

Updating the testcontainers dependency to 1.16.0.

Motivation and Context

We are seeing intermittent test failures in Jenkins like:

08:17:32 org.testcontainers.containers.ContainerLaunchException: Container startup failed

We've seen similar issues in the past, and they were resolved by updating testcontainers. This error disappeared for a long time, but now it is back. I would like to see if this resolves the issue. If we need to dig deeper, it will also help to be on the latest version.

How Has This Been Tested?

The new version of testcontainers doesn't publish all ports by default anymore.

testcontainers/testcontainers-java#4286
testcontainers/testcontainers-java#4263

It looks like OpenLDAPContainer.java isn't setting .withExposedPorts. It is being correctly set in NodeContainerFactory.java and MongoDBContainer.java.
