Enable thread amount config and pattern validation (#8)

The number of threads per process are now configurable via environment variables, and the QBiC measurement ID is now format validated in the registration request to fail early.

 ### Evaluation
 
-Last but not least, this step looks for any present QBiC measurement ID in the dataset name. If none
-is given, the registration cannot be executed.
+Last but not least, this step validates the QBiC measurement ID via a [configurable](#evaluation-step-config) regex pattern.
 
-In this case the process moves the task directory into the user's home error folder. After the user
-has
-provided a valid QBiC measurement id, they can move the dataset into registration again.
+In case of invalid measurement ID formats, the process moves the task directory into the user's home error folder.
+After the user has provided a valid QBiC measurement id, they can move the dataset into registration again.
+
+In case of a successful ID validation, the dataset will be moved to the configured destination folder.
+If multiple destination folders are provided in the [configuration](#evaluation-step-config), the assignment of the next target directory is based
+on a round-robin approach, to balance any downstream task load (e.g. openBIS dropbox registration).
