Drush 10 and drupal 8-9 ready hacks

Hi, based on your work I made some hacks to make it work with drupal 8 and 9. I decided to fork it as it change so much. The repo is in gitlab: https://gitlab.com/communia/check_drupal_8

A lot of changes are needed:
- Will use drush >=10.3.6 ( TBH i test with 10.3.5 patched with https://github.com/drush-ops/drush/commit/6889580cbc33ee4b359950ac32d6251f34f6c68d ).
- As drush needs to be in a drupal-project now and cannot be installed globally it changes the detection of drush also.
- Will use jq to parse the output in json of drush.
- Will use drush to get list of security updates.
- Will use composer to get list of outdated.
- A new "c" option is added to -w check for drupal status requirements, to allow to guess the global state of the drupal status requirements based on the information collected from all the items in status report: If there's any critical apply the critical, else if there's any warning apply the warning, else if everything is ok apply the OK.
- --check is replaced by -t and checks for drush, composer and jq.

You can check diff changes in https://gitlab.com/communia/check_drupal_8/-/commit/5bb5598414ba716c8fe192e9b94cc7c17f21fa6f .
Feel free to get the code to merge it back if needed!

thank's a lot!
