This commit adds a .builder.yaml file to each template directory. In the file
there is at the moment a single key/value pair, "default: <image>", where the
actual builder image name is <image>. Using a mapping allows the future
possibility that a user may specify a builder image by name via a flag on the
command line. For example,
```console
faas build --builder native
```
When a project is initialized, the .builder.yaml file is read, and the default
builder is saved in the project's .faas.yaml file. The .faas.yaml file is then
consulted when building an image with `faas build`. If the builder image is
specified, then the builder will use it. Otherwise, it will fallback to the
defaults. This allows developers to create custom builders, and specify them
in the configuration file.
After extracting the builder image from .builder.yaml in the project directory,
this file is deleted.
This commit also adds Verbose to the init command.
The CLI commands all printed confirmation prompts for the various flags
they exposed. This commit modifies that logic, so that there is no longer
a `-y` flag, but instead a `--confirm` or `-c` flag for each command, and
prompts are only displayed if using this flag. In most cases, the derived
values are printed even if not prompted for.
In call cases where the user is prompted, I have removed the "Verbose"
prompt, as that seems less like a configuration option that needs to be
confirmed, and more like just a CLI option for the current run which we
can just accept as-is.
The text for the prompts has also been reduced to one or two words.
Also added are some checks around image naming and repositories, short
circuiting failures that could occur if these are not specified or are
unknown. For example, if a user does `faas init` and then `faas deploy`
we don't yet know what the image name should be - one hasn't been built.

- Replaces globally-scoped formatter function with methods
- Defines enumerated Format types
- Renames the 'output' flag 'format' due to confusion with command file descriptors
- FunctionDescription now Function
- Global verbose flag replaced with config struct based value throughout
* feat: add init/build/deploy commands and customizable namespace
This commit comprises some fairly large changes in the codebase.
The 'create' command has been extracted into 'init', 'bulid' and
'deploy' commands. The 'create' command remains, but now delegates
most of its work to these other three. This also has resulted in
some rework of the various flags.
In addition, it is now possible to specify the cluster namespace to
which the function will be deployed.
