Option to stop all of the containers in the project

*Is your feature request related to a problem? Please describe.*
It seems to me that there's no other option to stop all the containers in a project except downing them. Since I can stop individual container in a project, it would be great to have an option to stop all containers, similarly like I can do U to up all of the services

*Describe the solution you'd like*
It would be great to have a keybinding like S to stop all of the containers in the project

*Describe alternatives you've considered*
none

*Additional context*
Downing the containers causes for instance my DB to be lost, which means after starting the project again I need to run all of my migrations, seeds etc. Now if I want to avoid that I need to either stop the containers one by one or exit the LazyDocker and run a command
