feat(plugins): New plugins for samtools and bedtools (#3574)

* Add first impl of samtools autocompletion

* Just autocomplete with files all the time

* Add init impl of bedtools completion

* Add readme.md for bedtools plugin

* Add readme for samtools

+# Bedtools plugin
+
+This plugin adds support for the [bedtools suite](http://bedtools.readthedocs.org/en/latest/):
+
+* Adds autocomplete options for all bedtools sub commands.
