This commit removes the undocumented, test used only, setting xpack.monitoring.collection.collectors. It should not be used by users at all, and has been initially created for collector tests.

The Elastic Secrets vault is served via HTTPS with a Let's Encrypt
certificate. The root certificate that cross-signed the Let's Encrypt
certificates were not trusted by the JDK until 8u101. This commit adds a
version check at the start of the build to make it clear the cause of
the underlying issue, and what the fix is.
