Some bash magic to generate the changelogs for lagom.

changelog.sh

#  Change Dir (cd) into the branch you want to release.
#  Set the value of "TAG='1.3.5'" to the latest tag in the branch you are releasing
#  The script uses `git log --pretty=format:"" START_HASH..HEAD` to list all commits between the $TAG and HEAD
#  The $TAG is converted into a HASH ID using `git show-ref --tags -d | grep "tags/$TAG^"\| awk -F\  '{print $1}'`
#  Of the returned log messages we grep to keep only those that include "(#999)" via `grep "(#"`
#  The output looks like:
#      Warn when describeServices is overridden (#847) Tim Moore
#      Fix typo (#845) Yuliana Apaza
#      Update sbt-conductr version to 2.3.5 in docs (#843) Ignasi Marimon-Clos
#      Travis injects values using env vars, not system props (#838) Ignasi Marimon-Clos
#      Run whitesource in Travis CI (#821) Ignasi Marimon-Clos
#      Issue #831, updated mentions of Production Suite to Enterprise Suite (#833) Ruth Stento
#  And that's rewritten using `sed` into:
