Fixes: #122
1. Made sending the "init" request in a separate process
2. If "init" request fails with STATUS_NOT_IMPLEMENTED or
STATUS_NOT_FOUND sets the progress to 100
3. Added `wait-finish` optional parameter to `app_api:app:register` occ
command.
What is missing:
- [x] Global option: how long the "/init" request can be proceed.
- [x] Docs update for this
- [x] Update nc_py_api CI for this
- [x] Added test for registering ExApp that does not have "/init"
endpoint.
This allows to implement ExApp without "/init" endpoint and made it
optional.
