Martin Atkins b217624d83 config/configupgrade: Test to show that list unwrapping works for sets
This was already working but we had no tests to prove it.

Martin Atkins e831182c8d plans/objchange: Hide sensitive attribute values in error messages
Since these error messages get printed in Terraform's output and we
encourage users to share them as part of bug reports, we should avoid
including sensitive information in them to reduce the risk of accidental
exposure.

James Bardin c20164ab31 fix CoerceValue to handle changing dynamic types
Objects with DynamicPseudoType attributes can't be coerced within a map
if a concrete type is set. Change the Value type used to an Object when
there is a type mismatch.

Martin Atkins bbbf22d8e4 configs/configschema: Block.StaticValidateTraversal method
This allows basic static validation of a traversal against a schema, to
verify that it represents a valid path through the structural parts of
the schema.

The main purpose of this is to produce better error messages (using our
knowledge of the schema) than we'd be able to achieve by just relying
on HCL expression evaluation errors. This is particularly important for
nested blocks because it may not be obvious whether one is represented
internally by a set or a list, and incorrect usage would otherwise produce
a confusing HCL-oriented error message.

James Bardin b3a491d035 use correct block types in CoerceValue
When creating Null or Unknown values during CoerceValue, the the outer
block type was being used rather than the current block type.

Martin Atkins 549544f201 configschema: Handle nested blocks containing dynamic-typed attributes
We need to make the collection itself be a tuple or object rather than
list or map in this case, since otherwise all of the elements of the
collection are constrained to be of the same type and that isn't the
intent of a provider indicating that it accepts any type.

Martin Atkins 0317da9911 plans/objchange: logic for merging prior state with config
This produces a "proposed new state", which already has prior computed
values propagated into it (since that behavior is standard for all
resource types) but could be customized further by the provider to make
the "_planned_ new state".

In the process of implementing this it became clear that our configschema
DecoderSpec behavior is incorrect, since it's producing list values for
NestingList and map values for NestingMap. While that seems like it should
be right, we should actually be using tuple and object types respectively
to allow each block to have a different runtime type in situations where
an attribute is given the type cty.DynamicPseudoType. That's not fixed
here, and so without a further fix list and map blocks will panic here.
The DecoderSpec implementation will be fixed in a subsequent commit.

James Bardin 8f295fcb22 CoerceValue should insert Null for unset attrs
This matches the decoder spec, where a value unset in the configuration
is always Null.

James Bardin 50e099ad10 don't set Unknown for computed values
Any value that is not set in the configuration should decode as a Null
value. Unknown should still be returned if a computed value expression
is unknown.

Martin Atkins d8bf3cc4e0 configschema: Fix ConfigSchema bugs with nested blocks
We were iterating over the wrong value to recursively coerce content for
nested blocks, and also incorrectly constructing the cty.Path used in
errors.

Martin Atkins 479c6b2466 move "configschema" from "config" to "configs"
The "config" package is no longer used and will be removed as part
of the 0.12 release cleanup. Since configschema is part of the
"new world" of configuration modelling, it makes more sense for
it to live as a subdirectory of the newer "configs" package.
