Remove extra quoting and instead add a backslach to each character in
the extra args before appending it to the command.
ex. atlantis plan -- -var key=val will result in:
sh -c "atlantis plan \-\v\a\r \k\e\y\=\v\a\l"
Fixes#697.
Features:
- remote plans and applies will set a commit status with a link to the
Terraform Enterpise UI where the streaming output can be viewed.
- because remote plans don't support the -out flag, we diff the plan
output between plan and apply phases to ensure users are applying the
plan they expected
How:
We add a new capability to execute a terraform command while
concurrently reading its real-time output and performing actions
accordingly.
If so, don't run plan with -out because this isn't currently supported.
Instead, write a planfile afterwards with the text contents of the plan.
During apply, detect that the planfile was generated using a remote plan
and run apply with -auto-approve and without the planfile arg which
isn't supported.
-target doesn't work with terraform apply when the apply is being run on
a planfile (which is how Atlantis runs plan). We should give the user an
error if they attempt this.
Fixes#399
