Epic: Replace identified `yapapi` bits to use `golem-core`

[approxit]

After #1096 , we know which bits of yapapi should be refactored to use golem-core, this is the time to actually refactor them.

Todo:

• [ ] Remove/replace identified bits to use golem-core instead of yapapi implementation
  • Refer to #1096 for identified bits
  • Not used yapapi code should be removed

### Bits
- [ ] https://github.com/golemfactory/yapapi/issues/1117
- [ ] https://github.com/golemfactory/yapapi/issues/1122
- [ ] https://github.com/golemfactory/yapapi/issues/1123
- [ ] GFTP provider and storage abstractions. Keep `webdev` storage but use abstraction from golem-core
- [ ] DEFAULT_DRIVER, DEFAULT_NETWORK, DEFAULT_SUBNET
- [ ] _YagnaDatetimeFormatter
- [ ] make yapapi's events not ued and remove them (are goth tests using those event?)
- [ ] make `worker` funciton use golem core's batches: remake Executor into a adapter so it uses golem core's batches
