A description of the changes proposed in the pull request:

This PR adds a config migration step for AMM, as well as disables the ability to configure a Pydantic strategy config while the strategy is running (which currently is not fully fleshed out and may lead to errors).

Tests performed by the developer:

• Manually tested the changes.

Tips for QA testing:

• For AMM migration
  • The migration should be able to migrate any configuration combination produced by the client in development
    • It is not required to handle cases where the user changed the values themselves to something that doesn't make sense (e.g. if a value is required, but the user removed it)
  • Please test all variations of the "modes"
• For the in-flight config disable
  • Please test that legacy configs act as they previously did
  • Test that the new Pydantic configs can be configured while the strategy is stopped, but must not be configurable when the strategy is running.
  • The global configs should be editable at all times.

Tested and confirmed working as expected when running from source, pending test on docker build. Currently blocked by the following error when starting a docker instance after creating a docker image based from the feature branch:

Traceback (most recent call last):
  File "bin/hummingbot_quickstart.py", line 18, in <module>
    from hummingbot.client.config.config_helpers import (
ImportError: cannot import name 'create_yml_files' from 'hummingbot.client.config.config_helpers' (/home/hummingbot/hummingbot/client/config/config_helpers.py)

Still hitting the issue Clinton flagged on creating a docker image.

This block testing on dockerbuild

Re-tested the PR and was able to create a docker container without the error mentioned above, however, got the following message in the background:

Despite this message in the background, I was able to start the strategies (including strategy that uses Kraken connector).

@RC-13, I have addressed the issue you flagged. Those messages should not appear anymore. Please test the migration and use of celo and kraken one more time. They should now migrate properly.

Latest commit looks good to me. I no longer see the last flagged error by Clinton. No notable error as well on connection/balance and running strategies on source and docker build.
