HADOOP-19544. Upgrade to Jackson 2.18.5

[pjfanning]

Description of PR

HADOOP-19544 replacing #7623

How was this patch tested?

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

[stoty]

It would be easier to use jackson-bom for version management.

[steveloughran]

or at least define jackson2.databind.version as ${jackson2.version} until some need to actually diverge surfaces again in future

[stoty]

See #8074 for the jackson-bom change.

[steveloughran]

+1 pending that build.

@stoty I see the BOM PR and think we can consider that separately; merge this in and then look at it.

[stoty]

Sure, the BOM change can be done independently either before or after

[pjfanning]

I don't know what happened to https://ci-hadoop.apache.org/job/hadoop-multibranch/job/PR-8070/1/

It looks like it failed but I'm not sure what the issue is.

[stoty]

I have restarted the CI job.
Looks like some transitent Jenkins issue

TestDelegatingSSLSocketFactory.testOpenSSL failure unrelated; #8071 fixes it. I just want a complete build there before the merge (it's already approved).
