Import configuration when migrating a cluster from Ansible

[yuzhibotao]

What problem does this PR solve?

From ansible to tiup ，there is no configuration parameter for the import action.

What is changed and how it works?

1. If the monitored_server is configured with deploy_dir and they are all the same, import deploy_dir into monitored_servers.
2. Add information about global parameters and component parameters of TiDB PD TiKV .
   After backing up the configuration files, parse the configuration files for each component, extract the same parameters into Server_Configs and put different parameters into the service's own Config.
