workdir: Start of a new package for working directory state management Thus far our various interactions with the bits of state we keep associated with a working directory have all been implemented directly inside the "command" package -- often in the huge command.Meta type -- and not managed collectively via a single component. There's too many little codepaths reading and writing from the working directory and data directory to refactor it all in one step, but this is an attempt at a first step towards a future where everything that reads and writes from the current working directory would do so via an object that encapsulates the implementation details and offers a high-level API to read and write all of these session-persistent settings. The design here continues our gradual path towards using a dependency injection style where "package main" is solely responsible for directly interacting with the OS command line, the OS environment, the OS working directory, the stdio streams, and the CLI configuration, and then communicating the resulting information to the rest of Terraform by wiring together objects. It seems likely that eventually we'll have enough wiring code in package main to justify a more explicit organization of that code, but for this commit the new "workdir.Dir" object is just wired directly in place of its predecessors, without any significant change of code organization at that top layer. This first commit focuses on the main files and directories we use to find provider plugins, because a subsequent commit will lightly reorganize the separation of concerns for plugin launching with a similar goal of collecting all of the relevant logic together into one spot.

Push plugin discovery down into command package Previously we did plugin discovery in the main package, but as we move towards versioned plugins we need more information available in order to resolve plugins, so we move this responsibility into the command package itself. For the moment this is just preserving the existing behavior as long as there are only internal and unversioned plugins present. This is the final state for provisioners in 0.10, since we don't want to support versioned provisioners yet. For providers this is just a checkpoint along the way, since further work is required to apply version constraints from configuration and support additional plugin search directories. The automatic plugin discovery behavior is not desirable for tests because we want to mock the plugins there, so we add a new backdoor for the tests to use to skip the plugin discovery and just provide their own mock implementations. Most of this diff is thus noisy rework of the tests to use this new mechanism.

cli: Remove legacy positional path arguments Several commands continued to support the legacy positional path argument to specify a working directory. This functionality has been replaced with the global -chdir flag, which is specified before any other arguments, including the sub-command name. This commit removes support for the trailing path parameter from most commands. The only command which still supports a path argument is fmt, which also supports "-" to indicate receiving configuration from standard input. Any invocation of a command with an invalid trailing path parameter will result in a short error message, pointing at the -chdir alternative. There are many test updates in this commit, almost all of which are migrations from using positional arguments to specify a working directory. Because of the layer at which these tests run, we are unable to use the -chdir argument, so the churn in test files is larger than ideal. Sorry!

command: make module installation interruptible Earlier work to make "terraform init" interruptible made the getproviders package context-aware in order to allow provider installation to be cancelled. Here we make a similar change for module installation, which is now also cancellable with SIGINT. This involves plumbing context through initwd and getmodules. Functions which can make network requests now include a context parameter whose cancellation cancels those requests. Since the module installation code is shared, "terraform get" is now also interruptible during module installation.
