Built-in data.txt plugin

[traut]

Background

There should be a way to import existing static text, stored in a separate text file, into a template. This use case covers the use of existing signatures, disclaimers, footers, etc, in a template.

Design

data.txt plugin should be a part of the fabric binary.

Specification

• the plugin has no configuration options
• API interface:
  • required path string attribute that accepts a path to a file on a local filesystem.

Behavior

Using the provided path value, the plugin reads the file and returns its body as its result. The file should be treated as a text file.

Deliverables

• new built-in data.txt plugin
• the unit tests for the plugin
