CLI: enhance the config command experience

[rugwirobaker]

Describe the solution you'd like

• Adding the -all flag to config command which would print all the variables set in that project.(ALREADY IMPLEMENTED by config get)

➜  ✗ waypoint config get -all
  SCOPE | NAME | VALUE  
--------+------+--------
        | PORT     |  8000  
        | PASSWORD | password
        | USERNAME | username
        | .....    | .....

• Also maybe a flag -raw to get the VALUES without the tabular format in case you want to pipe them to a file(.env)

➜ ✗  waypoint config get -all -raw | tee .env
PORT=8000  
PASSWORD=password
USERNAME=username

• Another welcome feature would be to be able to pipe KEY/VALUE pair in the form of KEY=VALUE to the config set command

➜  ✗cat .env |  waypoint config set

These are all good suggestions.

For the first suggestion: what do you mean "all the variables set in that project" ? Is this not how waypoint config get behaves today? I'm sure I'm misunderstanding something here.

Ohhh my bad I think it works.
