Remove user interaction for DWH prefix

[codemonkey2357]

-removed user interaction
-check_dwh_prefix() checks if matching database and wildfly servers are running. Therefore redundance in main() was removed
-also removed functions that were no longer needed

Deleting worked, but interactive option is removed and the containers are not checked if running. Find a way to incorporate both interactive and non-interactive execution (maybe by checking the command line arguments) and add the function to check if a container is running

[LongusBongus]

Sorry, Containers are being checked inside "check_dwh_prefix", then safely remove the function still calling "service_running"

The prefix selection is unintuitive (typing the number instead of the name, my bad). Change the requirement of the prefix preview: From now on the preview of currently running prefixes is just a helper. The main functionality will be, to type the preview by hand or write it into the script call. If the script needs to be terminated, use these logging-functions:

log_info() { echo -e "\033[0;34m[INFO]\033[0m $1"; }
log_success() { echo -e "\033[0;32m[SUCCESS]\033[0m $1"; }
log_warn() { echo -e "\033[1;33m[WARN]\033[0m $1"; }
log_error() { echo -e "\033[0;31m[ERROR]\033[0m $1" >&2; }

Definition of Done:

1. Script executes using sudo ./docker_delete_encounters.sh 20220101 20220201
2. Script executes using sudo ./docker_delete_encounters.sh 20220101 20220201 dwh1
3. Script terminates with status 1 and logs a Validation not successful comment, if given prefix did not meet requirements.

(these are just examples, replace with your own test dates and container prefix)

Other wise good job, core functionality is ready and seems stable.
