Suggestions on code formatting and add grumphp

Hi,

I Will be working on it.

MR has been created after fixing PHPCS errors. Please review.

Hi, I reviewed the MR and found many phpcs issues while running the command
phpcs --standard=Drupal --extensions=php,module,inc,install,test,profile,theme,css,info,txt,md,yml tmgmt_cdt/
So, changing the status to Needs work

Create a patch to fix the phpcs errors.
These errors are remaining:

$ phpcs --standard=Drupal --extensions=php,module,inc,install,test,profile,theme,css,info,txt,md,yml tmgmt_cdt/
