improve error message output

[tongueroo]

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

Error messages would get concatenated without newlines after max retries. This joins the final error message with newlines properly so it's readable.

Also added TS_MAX_RETRIES env variable ability.

Context

N/A

How to Test

One way to test is to go from an rather old version of terraform to the latest. If you have already ran terraspace up before, the state file structure is old enough to reproduce. Then running terraspace up with a newer version of Terraform will produce an error about state after terraspace max retries, which is 3. Can reproduce the error faster with:
