There are currently no checks on username and endpoint in the provider
schema from being an empty value. This PR adds support to make sure that
endpoint and username are not empty strings as that can cause a panic

When checking for "same" values in a computed hash, not only might some
of the values differ between versions changing the hash, but there may be
fields not included at all in the original map, and different overall
counts.
Instead of trying to match individual set fields with different hashes,
remove any hashed key longer than the computed key with the same base
name.
If an AWS Cookie Stickiness Policy is removed from the listener in
the AWS console the policy isn't deleted. Cross reference the policy
name with those assigned to the listener to determine if the policy
is actually being used.
Since this resource produces a list it feels more intuitive to give its
attribute a plural name, and since the noun "instance" already means
something specific in the AWS provider that doesn't apply here we use
"names" to indicate that these are availability zone names.
Also includes updating the docs to not show a dynamic count example for
now, since we don't support that yet.
When reading an AppCookieStickinessPolicy check for LoadBalancerNotFound
as well as PolicyNotFound. This prevents errors when when destroying a
policy on an ELB that no longer exists.
There were lots of hacky checks in the ARM VM resource to check for a
length of 1 param block
MaxItems was introduced so this PR updates to use MaxItems
This commit fixes a crash in `terraform show` where there is no primary
resource, but there is a tainted resource, because of the changes made
to tainted resource handling in 0.7.
The `concat()` interpolation function does not yet support types other
than strings / lists of strings. Make it an error message instead of a
panic when a list of non-primitives is supplied.
Fixes the panic in #7030
Dot indexing worked in the "regexps and strings" world of 0.6.x, but it
no longer works on the 0.7 series w/ proper List / Map types.
There is plenty of dot-indexed config out in the wild, so we need to do
what we can to point users to the new syntax.
Here is one place we can do it for user variables (`var.somemap`). We'll
also need to address Resource Variables and Module Variables in a
separate PR.
This fixes the panic in #7103 - a proper error message is now returned.
Previously, interpolation of multi-variables was returning an empty
variable if the resource count was 0. The empty variable was defined as
TypeString, Value "". This means that empty resource counts fail type
checking for interpolation functions which operate on lists.
Instead, return an empty list if the count is 0. A context test tests
this against further regression. Also add a regression test covering the
case of a single count multi-variable.
In order to make the context testing framework deal with this change it
was necessary to special case empty lists in the test diff function.
Fixes#7002
