Updates the Terraform getting started guide to reflect the use of a
custome provider registry:
* Removes the now-superfluous installation step
* Updates examples to reflect actual location of terraform provider
Most of the changes are related to the strictness of TF v0.12

> Due to the design of the configuration language decoder in

> (with just braces) when dealing with map arguments vs. nested
> blocks. However, this led to some subtle bugs and limitations,
> so Terraform v0.12 now requires consistent usage of argument
> syntax for arguments and nested block syntax for nested blocks.

Terraform Provider guide
- Add tabbed prerequisites so users only see information relevant to
their scopes.
- Add the impersonation section as an H3 rather than an Admonition. If
users are learning how to use our Terraform provider, they likely
will not have enabled impersonation for the Terraform user, and would
always need to read the Admonition, so this would work better as an
H3.
- Add a scoped Notice indicating which address to use for the cluster
address in the sample Terraform config.
Fluentd plugin guide
- Add tabbed instructions for users of different scopes.
- Move the impersonation Admonition to an H3 so readers can configure
impersonation without running into an error.
- Misc clarity/style edits.
Certificate Authority Rotation
- Add tabbed prerequisites so users of one scope don't see information
intended for other scopes.
