@parasjain1 Is this targeting 2.11 release?

[parasjain1]

@DarshitChanpura yes this is targeting 2.11 release.

FYI BWC tests are failing due to compilation failures. Seems like the recent fixes were not backported to 2.x.

• While resolving conflicts, I've not brought in any changes to the CI configuration. Please see if we need to bring those in, feel free to open a separate PR if needed.
• I've updated the ConfigConstants.FIRST_CUSTOM_SERIALIZATION_SUPPORTED_OS_VERSION to 2.11.0 in this PR and accordingly also updated the versions in SecuritySSLRequestHandlerTests.

[cwperks]

@parasjain1 The compilation failures are due to a difference in the version of the Apache HttpClient/HttpComponent libraries used in main vs 2.x. main uses HttpClientV5 while 2.x uses HttpClientV4. This PR will need to adjust to the difference between the main and 2.x branch of the security plugin.
