Instead of using a hardcoded version prerelease string, which makes release automation difficult, set the version prerelease string from an environment variable via the go linker tool during compile time.
The environment variable `TF_RELEASE` should only be set via the `make bin` target, and thus leaves the version prerelease string unset. Otherwise, when running a local compile of terraform via the `make dev` makefile target, the version prerelease string is set to `"dev"`, as usual.
This also requires some changes to both the circonus and postgresql providers, as they directly used the `VersionPrerelease` constant. We now simply call the `VersionString()` function, which returns the proper interpolated version string with the prerelease string populated correctly.
`TF_RELEASE` is unset:

During an instance shut-down network interfaces may be detached during the `READ` method of a Terraform run.
This protects the case where a network interface was detached, and is now `nil` at the time of the Terraform run, fixing nil pointer dereferences.
This commit catches an error when the instance is parsing and building
its network list. This can happen when a cloud provider responds with
a non-JSON response for the list of networks.
Previously lightsail was limited to `us-east-1` only. This restriction has now been lifted to new regions.
