faa77b77c8 Support for custom shells
It is now possible to override and explicitly specify the shell you
would like used when executing cron tasks. This is accomplished with the
NEXTCLOUD_EXEC_SHELL environment variable, which defaults to bash. You
can also override and customize the arguments provided to that shell
executable via NEXTCLOUD_EXEC_SHELL_ARGS, which defaults to "-c".

See documentation for more detail and examples.

Fixes #6

08ec92f509 Add extra logs and debugging features
* New DEBUG environment variable enables `set -x` in shell scripts for
  extra verbose output for debugging custom cron scripts and to assist
  with development of the core scripts.
* Verify if we can find the Nextcloud container on start up. Fail if
  not.
* Print information about how we will search for Nextcloud on start up.
* During cron task execution, the ID of the Nextcloud container is
  printed, if found.

6416dd8731 Cronjob works now between Nextcloud container recreation
If the Nextcloud container is recreated while the cronjob container is still running, the ID of the
container is obtained each time the cron tasks are executed. Previously it was cached on entrypoint,
so if the ID changed this container would fail.

Allow configuration of user used for task execution
New NEXTCLOUD_EXEC_USER environment variable added which allows control over which
user is used to execute cron tasks inside the Nextcloud container. By default, the
user is `www-data`. If the environment variable is specified but empty, no `--user`
option is provided to `docker exec`.

ab6372fa79 Provide the ability to run user-defined cron tasks
Mount individual shell scripts (with the `*.sh` extension) inside `/cron-scripts/` in the
container. The cron daemon will automatically run these scripts inside the Nextcloud
container for you. Write the scripts as if they will run in the Nextcloud container
itself.
