Add support for CLOUDFLARE_API_HOSTNAME

[manatarms]

Allows for talking to hostnames other than api.cloudflare.com

within the library, we already have this configuration option, unfortunately named BaseURL -

cloudflare-go/options.go

Line 87 in 8f84ec3

// BaseURL allows you to override the default HTTP base URL used for API calls.

here is an example of it in action within the Terraform provider - https://github.com/cloudflare/terraform-provider-cloudflare/blob/f948788352200cba83d07e107e775b3645d68416/cloudflare/provider.go#L201

both of these are available in released versions too so that should cover everything.

hope this helps!

the library example can be seen in the initial PR (#606) too as the options can be a little confusing to use.

I'm mostly doing this so that cf-terraforming uses the same hostname ENV as terraform. I can probably do this in cf-terraforming itself.
I'll add it to my current PR cloudflare/cf-terraforming#331

[jacobbednarz]

that’s probably the best way. the other two places (Go library and Terraform) have support for this so cf-terraforming just needs it.
