Hapify config generation

This package provides a new way of expriming hapify configuration. It adds a new
way to extend the hapify configuration. To work with the current version of
hapify it takes a configuration to generate a hapify.json files. In order to
do that it provides a list of files to read your new and shiny configuration and
take the first file found in this order:

``js
[
'.hapifyrc.js',
'.hapifyrc.yaml',
'.hapifyrc.yml',
'.hapifyrc.json',
'.hapifyrc',
'package.json',
'hapify.json',
];
`

It adds the extends array property that specifies other hapify templates
packages, concat theirs configurations, and copy all the files needed to the
current hapify folder. In order to generate all these steps you only need to
start the following command:

`bash
npx hpf-generate-config
`

Extends configuration examples:

`js
// .hapifyrc.js
module.exports = {
extends: [
'@trxn/hapify-templates-prisma',
'@trxn/hapify-templates-nestjs-models',
// ...
],

// ... all your hapify configuration
};
`

> Note: this package is intended to be deleted until hapify integrates the
> extends` options. The copy and the generated configuration is not the best
> way to do and this package is just a patch to accelerate developement of the
> new stack
