[feature] better bash completion for -target and -options

[Kamilcuk]

Terraform Version

Terraform v1.9.3

Use Cases

The use case is any command typed in the terminal.

Attempted Solutions

No solution has been found. The solution could be parsing terraform files myself and finding the answer.

Proposal

I propose to bash-complete the -option of terraform commang line tool:

$ terraform apply -auto-<TAB>
->
$ terraform apply -auto-approve

Additionally I propose to bash-complete the target names:

$ terraform apply -target=nomad_job.something<TAB>
nomad_job.something_a nomad_job.something_b
$ terraform apply -target=nomad_job.something
