Current Behavior

As reported in #33 - service can not handle the insertion if only a single CPU\worker is available.

Steps to Reproduce

1. Run Qdrant with docker run --rm -it --cpuset-cpus=0 -p 6333:6333 generall/qdrant
2. Create collection
3. Insert vector into the collection with ?wait=true
4. Service is not responding

Expected Behavior

Should work with a single core same as with multiple cores.

Possible Solution

Do not create less than 2 workers even is a single CPU is available
