upgraded spring boot starter version

added gson dependency
added logging the exception in the exception post executor
added configuration exception in case the configuration for posttargets is not correct
added support to send embeds to posttargets
changed interface to be a warnlog instead of a server context for warning users, because the template
changed freemarker Incompatible Improvements to support default methods in interfaces
added ability to define embed configurations to be used, in order for a template to only be configurable as a template
changed template content size to 4000 characters
