Based on some feedback on the initial draft, make some minor updates to
how information is presented in the preview upgrade guide for v0.12.
This also includes some minor copy-editing work to try to make the "voice"
more consistent between different sections of the guide.
Following the examples as they were previously would cause errors
accessing demo.consul.io. Now we consistently set the scheme to https for
all examples that use demo.consul.io.
This also includes some other updates to the URLs, since the Consul demo
has been rebuilt with a different based configuration, and some general
formatting and copyediting changes in the Consul example.
This is a genre of invalid output expression that we've seen quite
commonly while testing with 0.11.0-rc1, so we'll call it out specifically
in the upgrade guide and suggest how to fix it.
We are recommending that as of 0.11 all provider configurations be placed
in the root module and, where necessary, be explicitly passed down via
a providers map to customize which configurations are seen by each
child module.
This new section attempts to guide users through such refactoring in the
common case where a child module defines its own provider configuration
based on a value passed in an input variable, and then uses that as
some context to link to the more detailed docs to help those who have
more complex configurations.
This changed close to the release of beta1 to use underscores as the
separator and to use a lower-case "v" to avoid any issues on
case-insensitive filesystems.
