Fix: Use correct ignore file for beta9 and beam cli commands (#818)

Previously, commands would always get the default sdk settings. This was
caused because importing `sync.py` caused the default settings to be
loaded no matter what. Now, we don't set `_settings` in `sync.py` and
instead access it indirectly so that importing sync doesn't initialize
settings with defaults. When "beam" is included in the modules, we load
the beam config instead of the default beta9 config.

Old behavior:
```bash
~/Dev/beam/bs/endpoint ❯ beam deploy app.py:handler                                        
=> Building image 
=> Using cached image 
=> Syncing files 
Reading .beta9ignore file  # WRONG
```

New behavior: 
```bash
~/Dev/beam/bs/endpoint ❯ beam deploy app.py:handler                                     
=> Building image 
=> Using cached image 
=> Syncing files 
Reading .beamignore file  # CORRECT
```
