Introduce gp command to add env from .env file

[thisisommore]

Is your feature request related to a problem? Please describe

When we have .env file with variables already there and we want to persist that in gitpod way using gp env we have to manually run the command gp env KEY=value for each variable, which decreases my productivity for setting new repos

Describe the behaviour you'd like

I would like to run command which reads and specified file like .env and persist that key and values of environment variables for that repo, like what gp env does.
For example

$ gp env-read .env
> 13 Environments added

Describe alternatives you've considered

Hey @thisisommore 👋

As a workaround for now you can use the following to save your time:

while read -r line; do {
   [[ ! "$line" =~ ^\# ]] && gp env "$line";
} done < .env

@axonasif can this be never stale?

@thisisommore let's comment each time when stalebot tries to close this issue 🙂

[thisisommore]

@axonasif can we add meta: never-stale instead 😃

[axonasif]

I added it to one of your other issue that was also stale.

@axonasif I don't get it
So this issue will also act as never stale?
Are this two(this and one #12877) issues linked anywhere?
