addrs: replace "Type string" with "Type Provider" in ProviderConfig
* huge change to weave new addrs.Provider into addrs.ProviderConfig
* terraform: do not include an empty string in the returned Providers /
Provisioners
- Fixed a minor bug where results included an extra empty string

Martin Atkins 39e609d5fd vendor: switch to HCL 2.0 in the HCL repository
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.

This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.

For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.

Martin Atkins f77e7a61b0 various: helpers for collecting necessary provider types
Since schemas are required to interpret provider, resource, and
provisioner attributes in configs, states, and plans, these helpers intend
to make it easier to gather up the the necessary provider types in order
to preload all of the needed schemas before beginning further processing.

Config.ProviderTypes returns directly the list of provider types, since
at this level further detail is not useful: we've not yet run the
provider allocation algorithm, and so the only thing we can reliably
extract here is provider types themselves.

State.ProviderAddrs and Plan.ProviderAddrs each return a list of
absolute provider addresses, which can then be turned into a list of
provider types using the new helper providers.AddressedTypesAbs.

Since we're already using configs.Config throughout core, this also
updates the terraform.LoadSchemas helper to use Config.ProviderTypes
to find the necessary providers, rather than implementing its own
discovery logic. states.State is not yet plumbed in, so we cannot yet
use State.ProviderAddrs to deal with the state but there's a TODO comment
to remind us to update that in a later commit when we swap out
terraform.State for states.State.

A later commit will probably refactor this further so that we can easily
obtain schema for the providers needed to interpret a plan too, but that
is deferred here because further work is required to make core work with
the new plan types first. At that point, terraform.LoadSchemas may become
providers.LoadSchemas with a different interface that just accepts lists
of provider and provisioner names that have been gathered by the caller
using these new helpers.

Martin Atkins 2eba023537 configs: NewEmptyConfig function
This is useful for creating a valid placeholder configuration, but not
much else. Most callers should use BuildConfig to build a configuration
that actually has something in it.

Martin Atkins cd51864d84 configs: Start using the new "addrs" package types for modules
We initially just mimicked our old practice of using []string for module
paths here, but the addrs package now gives us a pair of types that better
capture the two different kinds of module addresses we are dealing with:
static addresses (nodes in the configuration tree) and dynamic/instance
addresses (which can represent the situation where multiple instances are
created from a single module call).

This distinction still remains rather artificial since we don't yet have
support for count or for_each on module calls, but this is intended to lay
the foundations for that to be added later, and in the mean time just
gives us some handy helper functions for parsing and formatting these
address types.

Martin Atkins ebafa51723 command: Various updates for the new backend package API
This is a rather-messy, complex change to get the "command" package
building again against the new backend API that was updated for
the new configuration loader.

A lot of this is mechanical rewriting to the new API, but
meta_config.go and meta_backend.go in particular saw some major
changes to interface with the new loader APIs and to deal with
the change in order of steps in the backend API.

Martin Atkins 72ad927c4d configs/configload: package for loading configurations
Previously the behavior for loading and installing modules was included in
the same package as the representation of the module tree (in the
config/module package).

In our new world, the model of a module tree (now called a "Config") is
included in "configs" along with the Module and File structs. This new
package replaces the loading and installation functionality previously
in config/module with new equivalents that work with the model objects
in "configs".

As of this commit, only the loading functionality is implemented. The
installation functionality will follow in subsequent commits.

Martin Atkins 8929eca405 configs: BuildConfig function
BuildConfig creates a module tree by recursively walking through module
calls in the root module and any descendent modules. This is intended to
be used both for the simple case of loading already-installed modules and
the more complex case of installing modules inside "terraform init", both
of which will be dealt with in a separate package.

Martin Atkins 13fa73c63e configs: stub out main configuration structs
These types represent the individual elements within configuration, the
modules a configuration is made of, and the configuration (static module
tree) itself.
