Add --project-name flag to olmcatalog gen-csv

At present `operator-sdk gen-csv` command takes the base driectory name
as the operator name while generating CSV

This patch adds a flag `--project-name` to specify the operator name
while generating CSV using `operator-sdk gen-csv` command

The default value (when flag is absent) is base directory name as before
