FINERACT-2219: capture v1.11.0 lessons learned in asciidoc and fineract release plugin

* don't bother making MD5 files, they aren't necessary
* step12 changed, stub it out and reference FINERACT-1817 for future improvements (looks like svn mv is not yet supported)
* use latest vote message template, based on https://lists.apache.org/thread/cs5t0ho39ktg2jxr74dqd7fg9nyfcz3k
* use more explicit form of `git push` to push release tag, see https://stackoverflow.com/questions/5195859/how-do-you-push-a-tag-to-a-remote-repository-using-git
* use consistent language re: tarball, file, artifact, release candidate
* fix some source listings that shouldn't be using macro expansion: this messes up URLs (hides scheme)
* fix asciidoc link to FINERACT-1229
* clean up copyright years: use variable properly and remove unnecessary extra copyright in preface (it appears directly above, in the license)
* de-indent URL in apache license -- this makes the link clickable in rendered HTML and PDF asciidoc outputs
