Add support for train without specify pretrained model, add support for selecting v2 48k as training setting, and add support for auto remove pretrained model when the user do not have pretrained model in designate folder. (#528)

* support detection of pretrained model, support train without pretrained model path in web ui

* support detection of pretrained model, support train without pretrained model path in web ui

* support detection of pretrained model, support train without pretrained model path in web ui
