Configuration option --server-process-count does not work

[toni-sissala]

When starting the application with

python -m cdcagg_oai\
 --document-store-url "http://localhost:5001/v0"\
 --oai-pmh-admin-email admin@email.com\
 --oai-pmh-base-url baseurl\
 --server-process-count 1\
 --loglevel INFO

the log outputs (with a server with two processor cores)

[...]
"message": "Starting 2 processes"
[...]

Also, the process listing outputs three python processes: one parent and two children.
