Upgrade jberet-core from 1.3.3.Final to 1.3.4.Final

Need to upgrade jberet-core from the current version 1.3.3.Final to 1.3.4.Final, to include the fix that ensures https (instead of http) is used in maven repository links.

https://github.com/jberet/jsr352/tree/1.3.x

Delta: https://github.com/jberet/jsr352/compare/1.3.3.Final...1.3.4.Final
The real changes that affect jberet-core are:

• upgrade jboss-parent to 34
• upgrade jboss-logging to 3.4.0
• upgrade jboss-batch-api_1.0_spec to 1.0.2 (which was built with secure https maven repository links)
• change to use https for maven repository links in build process
