Provide does not use the region defined in AWS profile

[mikhailshilkov]

What happened?

We expect AWS region to be defined in the stack config, or in AWS_REGION or AWS_DEFAULT_REGION environment variables. If none is defined, we throw an error: https://github.com/pulumi/pulumi-aws-native/blob/b962c3b2c972f570ab96c9003748f124178615f6/provider/pkg/provider/provider.go#L288-L296

However, it's possible to define a region in user's AWS profile. The AWS Classic provider respects that configuration, and AWS Native should do the same. Unfortunately, the profile check happens later in the code: https://github.com/pulumi/pulumi-aws-native/blob/b962c3b2c972f570ab96c9003748f124178615f6/provider/pkg/provider/provider.go#L298

Example

[MyAwsProfile]
region = eu-central-1
... other AWS profile configuration

@mikhailshilkov do you know what the priority of this one is? Is it something we should fix this iteration or next?

[mikhailshilkov]

@corymhall It'd be nice to fix, but I don't have any strong timeline signal.
