Rename CLOUDAMQP_URL variable

[dustinturp84]

I noticed that CLOUDAMQP_URL is used a lot in our documentation for holding the AMQP connection string. To avoid conflicts with the CLI and our docs example code I propose a change in client/client.go from CLOUDAMQP_URL to CLOUDAMQP_API_URL or CLOUDAMQP_API_BASE_URL

cli/client/client.go

Line 25 in 5458022

if envURL := os.Getenv("CLOUDAMQP_URL"); envURL != "" {

The CLI is not satisfied with CLOUDAMQP_URL emptied and will attempt to use the AMQP connection string if set.

Happy to create a PR if this is accepted or other way to handle the env conflicts.

Yeah, agree, CLOUDAMQP_API_URL sounds good to me.
