Messages "Acquiring lock" and "Release lock" are printed to stdout instead of stderr with terraform console which breaks parsing.

Terraform Version

bash-3.2$ terraform -v
Terraform v0.11.9
+ provider.archive v1.1.0
+ provider.aws v1.36.0
+ provider.external v1.0.0
+ provider.null v1.0.0
+ provider.template v1.0.0
+ provider.tls v1.2.0

Expected Behavior

When I run echo var.project_name|terraform console I expect to see only value of var.project_name on stdout. Everything else (errors, warnings, etc.) should go to stderr.

Actual Behavior

If the lock or unlock request takes more that 400ms, additional messages are being added to stdout:

bash-3.2$ VAR=`echo var.project_name|terraform console`; echo "[${VAR}]"
[projname
Releasing state lock. This may take a few moments...]

Steps to Reproduce

Just run terraform console with slow network and/or when AWS services are slow to respond.

The corresponding code seems to be located here:

terraform/command/clistate/state.go

Line 122 in 1dc3e50

l.ui.Output(l.color.Color(LockMessage))

and

terraform/command/clistate/state.go

Line 145 in 1dc3e50

l.ui.Output(l.color.Color(UnlockMessage))

.

I have this problem also, really irritating when you want to do additional things in CI process....
