fix terraspace output and Enter a value handling

[tongueroo]

• Fix terraspace output to not add extra newlines properly
• Handle stdin prompt "Enter a value" properly.
• Seems like handling the extra newlines properly fixes the prompt.

This is a 🐞 bug fix.

• I've added tests (if it's a bug, feature or enhancement)
• I've adjusted the documentation (if it's a feature or enhancement)
• The test suite passes (run bundle exec rspec to verify this)

Summary

• Fixes terraspace output STACK -json | jq for stacks with really large output properly. Related Fix terraspace output to not add extra newlines #139
• Also, improved stdin "Enter a value:" prompt handling. No longer mimic-ing it with Terraspace.

Context

• Fix terraspace output to not add extra newlines #139
• Terraspace show --json adds newlines to json output #126

How to Test

Find a stack that produces rather large output. Compare the terraspace show vs terraform show output. They should be exactly the same. Example:

$ terraspace show vpc --json > /tmp/a.json
Building .terraspace-cache/us-west-2/dev/stacks/vpc
Built in .terraspace-cache/us-west-2/dev/stacks/vpc
Current directory: .terraspace-cache/us-west-2/dev/stacks/vpc
=> terraform show -json
$ cd .terraspace-cache/us-west-2/dev/stacks/vpc ; terraform show -json > /tmp/b.json ; cd -
$ diff /tmp/a.json /tmp/b.json
$ 

Also, do a sanity check that terraspace up and terraspace down work.
