James Nugent 706ccb7dfe core: Introduce state v3 and upgrade process
This commit makes the current Terraform state version 3 (previously 2),
and a migration process as part of reading v2 state. For the most part
this is unnecessary: helper/schema will deal with upgrading state for
providers written with that framework. However, for providers which
implemented the resource model directly, this gives a best-efforts
attempt at lossless upgrade.

The heuristics used to change the count of a map from the .# key to the
.% key are as follows:

    - if the flat map contains any non-numeric keys, we treat it as a
      map
    - if the map is empty it must be computed or optional, so we remove
      it from state

There is a known edge condition: maps with all-numeric keys are
indistinguishable from sets without access to the schema. They will need
manual conversion or may result in spurious diffs.

James Nugent 3ea3c657b5 core: Use OutputState in JSON instead of map
This commit forward ports the changes made for 0.6.17, in order to store
the type and sensitive flag against outputs.

It also refactors the logic of the import for V0 to V1 state, and
fixes up the call sites of the new format for outputs in V2 state.

Finally we fix up tests which did not previously set a state version
where one is required.

James Nugent 6aac79e194 state: Add support for outputs of multiple types
This commit adds the groundwork for supporting module outputs of types
other than string. In order to do so, the state version is increased
from 1 to 2 (though the "public-facing" state version is actually as the
first state file was binary).

Tests are added to ensure that V2 (1) state is upgraded to V3 (2) state,
though no separate read path is required since the V2 JSON will
unmarshal correctly into the V3 structure.

Outputs in a ModuleState are now of type map[string]interface{}, and a
test covers round-tripping string, []string and map[string]string, which
should cover all of the types in question.

Type switches have been added where necessary to deal with the
interface{} value, but they currently default to panicking when the input
is not a string.

Paul Hinze 6bafa74011 tests: allow opt-out of remote tests via env var
Adds the `TF_SKIP_REMOTE_TESTS` env var to be used in cases where the
`http.Get()` smoke test passes but the network is not able to service
the needs of the tests.

Fixes #4421

Paul Hinze 6aa5fdc938 state/remote/atlas: handle conflicts on equivalent states
Atlas returns an HTTP 409 - Conflict if the pushed state reports the same
Serial number but the checksum of the raw content differs. This can
sometimes happen when Terraform changes state representation internally
between versions in a way that's semantically neutral but affects the JSON
output and therefore the checksum.

Here we detect and handle this situation by ticking the serial and retrying
iff for the previous state and the proposed state:

  * the serials match
  * the parsed states are Equal (semantically equivalent)

In other words, in this situation Terraform can override Atlas's detected
conflict by asserting that the state it is pushing is indeed correct.
