Reverting JOYSTICK_THROTTLE_DIR to v3 default

Set USE_JOYSTICK_AS_DEFAULT to False in cfg_complete.py

In v3 it is `-1.0`.

Improvements in tub and training to manage new datastore and new tub GUI

Fix tflite input/output conversion.

Add performance monitor

This is the default in v3. Setting this to `True` by default will not activate the web controller and caused some confusion to users.

myconfig.py default scene name fix

Add back training history plot

Patch to #752 - fix wrong operator in pip.

Add missing `DEFAULT_AI_FRAMEWORK`. `donkey train` won't run without this.

* Rename ubuntu.yml to pc.yml and update docs accordingly.

* Added missing update in travis.

Fixed FindCar function for RPi4

* Renamed function for session id creation in manifest and stored dictionary of last_id, last_full_id and all_full_ids in the metadata so no parsing needs to happen. Added more comment to the manifest to explain the session id logic. Added `if` around session_id update flag, so flag gets set only once.
* Reverted tub test and created new tub writer test instead
* Removed shutdown hook from tub writer as it will be closed by the vehicle
* When session_id data gets inserted into the metadata, only modify the corresponding line (actually the seekable also modifies the lines below, there is still room for improvement in that method)
* Minor performance upgrades and improved timing in fast forward loop in UI
