Specify installation paths for repositories

You can set individual installation paths for any Git repositories you declare in a Puppetfile.

The :install_path option allows you to separate non-module content in your directory structure or to set specific installation paths for individual modules. When you set this option for a specific repository, it overrides the moduledir setting (which is either the default modules directory or a custom path if you Change the module installation directory).

In your Puppetfile, under the Git repository's mod directive, use the :install_path option to declare the location where you want to install the content. The path must a string and it must be relative to the Puppetfile's location. To install in the root directory, specify an empty value.
Content is installed into a subdirectory named after to the content's mod directive. For example, this declaration installs site data content from a Git repository into the ./hieradata directory:
```
mod 'site_data', 
    :git => 'git@git.example.com:site_data.git',
    :install_path => 'hieradata'
```
The final file path for this content is ./hieradata/site_data.
As another example, this declaration installs site data content from a different Git repository into a site_data directory at the root:
```
mod 'site_data_2',
  :git => 'git@git.example.com:site_data_2.git',
  :install_path => ''
```
The final file path for this content is ./site_data.
