cli/command/completion: add EnvVarNames utility
EnvVarNames offers completion for environment-variable names. This
completion can be used for "--env" and "--build-arg" flags, which
allow obtaining the value of the given environment-variable if present
in the local environment, so we only should complete the names of the
environment variables, and not their value. This also prevents the
completion script from printing values of environment variables
containing sensitive values.

For example;

    export MY_VAR=hello
    docker run --rm --env MY_VAR alpine printenv MY_VAR
    hello

Before this patch:

    docker run --env GO
    GO111MODULE=auto        GOLANG_VERSION=1.21.12  GOPATH=/go              GOTOOLCHAIN=local

With this patch:

    docker run --env GO<tab>
    GO111MODULE     GOLANG_VERSION  GOPATH          GOTOOLCHAIN
