Add Git Commit Message Template to the Repository (#94)

* Add git commit message template to the repository
  * Why:
    * This helps to have a common commit message structure,
    * This also helps to identify problems while writing the answers to these questions.
  * Changes to be committed:
    * new file:   .gitmessage
* Add repository git config that includes the git commit message template
  * What:
    * This file needs to be included by each developer using the local command to have it repository dependent
  * Use:
    * git config --local include.path ./.gitconfig
  * Changes to be committed:
    * new file:   .gitconfig
