Support reset factory in Sonic OS
[Reset Factory HLD](https://github.com/sonic-net/SONiC/pull/1231)
[Sonic-mgmt tests](https://github.com/sonic-net/sonic-mgmt/pull/7652)
#### How I did it
- Added new script "/usr/bin/reset-factory"
* It generates a new config_db.json files with factory configurations
* It clears system files and logs
* It removes all docker containers on system except database
* It clears non-default users and restores default users password
- Dump the default users info to a new file during build "/etc/sonic/default_users.json"
- Supported new type "Keep-basic" in "config-setup factory"
- Add new conf file for config-setup "/etc/config-setup/config-setup.conf
#### How to verify it
- Run reset-factory script with all types: < none | keep-all-config | only-config | keep-basic >
- Run config-setup factory with parameters < none | keep-basic >
