Allow for multiple experiments and runs out of the box

Is your feature request related to a problem? Please describe.
Monai bundle should allow for multiple experiments and runs out of the box

Describe the solution you'd like
In the train.config

• Add "folder_name": "experiment1"
  this should lead to
• creating a new folder in models/experiment1
• Make new model, tensor board etc be generated in this new folder
• Copy the train.json and train_continues.json into this folder for tracking
• direct the log file to be generated into this new folder

Describe alternatives you've considered
I have modified the bundle myself to do some of this. however I need to give the same folder name in the train and in the logging.config

Additional context
the infer.config should be modified to take parameters from the train.json files specifically the intenisty range , resolution etc
I couldn't get this to work. I tired

• passing in the train.json gave errors
• changed parameters in the infer.json to use the filepath#parametername didn't work as the train.json is in subfolder model/experiment1
• copying the infer.json into the new folder model/experiment1 but I got errors related to path

Start by tracing how train.config, logging.config, train.json, and train_continues.json are handled when a bundle runs. Review the infer.config/infer.json parameter references and the model/experiment1 path behavior. Done means multiple runs create an experiment folder containing models, TensorBoard output, logs, and copied training configs, while inference can use the recorded training parameters.
