Rename binary from 'coder' to 'coop'

[hh]

The cli name should reflect that it is cooperations we create, list, show.

Coders can help create cooperations in our local neighborhoods globally!

As a human
I want to cooperate with others
In order to go far together

Given a template for cooperation
When I run `coop template create neighbor`
Then I create a template for cooperation

Given a two or more humans with shared values
When I run `coop create neighborhood --with-template="neighbor"`
Then I create a neighborhood cooperation

[hh]

Let's look at our first changes to the repo here. I'd like us to generate binaries named coop instead of coder. Let's take this time to understand how coder binaries and packages are generated so we can build both slim and fat binaries.

The build process for the fat binaries will load in cloudnative-coop/coop-templates.
