docs: convert docs to ReST and rename to *.rst

The conversion is actually:
  - add blank lines and indentation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

-dm-queue-length
-===============
-
-dm-queue-length is a path selector module for device-mapper targets,
-which selects a path with the least number of in-flight I/Os.
-The path selector name is 'queue-length'.
-
-Table parameters for each path: [<repeat_count>]
-        <repeat_count>: The number of I/Os to dispatch using the selected
-                        path before switching to the next path.
-                        If not given, internal default is used. To check
-                        the default value, see the activated table.
-
-Status for each path: <status> <fail-count> <in-flight>
-        <status>: 'A' if the path is active, 'F' if the path is failed.
-        <fail-count>: The number of path failures.
-        <in-flight>: The number of in-flight I/Os on the path.
-
-
-Algorithm
-=========
-
-dm-queue-length increments/decrements 'in-flight' when an I/O is
-dispatched/completed respectively.
-dm-queue-length selects a path with the minimum 'in-flight'.
-
-
-Examples
-========
-In case that 2 paths (sda and sdb) are used with repeat_count == 128.
