[Feature Request] Documentation for FIPS configuration

[whgibbo]

Is your feature request related to a problem? Please describe

Looking for clarification if OpenSearch 3.x can be configured for FIPS only algorithms.
From what I can see:

• the BouncyCastle FIPS jars are included in the docker image
• usr/share/opensearch/config/java.security is configured to Bouncy castle

But can't find any documentation references to on how to enable this.

I'm assuming that just setting the JVM OPTS could be enough..

Describe the solution you'd like

It would be good for any or all of the following:

• introduce documentation to indicate if FIPS is support and what level.
• introduce a parameter for the docker file to enable FIPS, which would the utilize the correct java.security file.

Describe alternatives you've considered
