Feature Request: Commonly used environment variables

[phulstaert]

When creating a new container, it would be nice if the commonly used environment variables were shown. Also the commonly used paths and such..

When people use the app, we could capture the used "options" (not the value itself, only the used variable) and could how often it is used.
Then, when a certain threshold of inputs is passed, you could suggest these if for example more then 80% of people use these variables.

Ex:
I add a mariadb container.
I get the suggestions to create environment variables for a user, user password, root password, default databasename, ...
But also a suggestion to create a volume or relative path to "/var/lib/mysql"

This speeds things up and helps us, so we don't forget something. (or at lease less likely to forget something)
