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.
