Migrator
--------
**Summary:** migrate old versions of cloud-init data to new

This module handles moving old versions of cloud-init data to newer ones.
Currently, it only handles renaming cloud-init's per-frequency semaphore files
to canonicalized name and renaming legacy semaphore names to newer ones. This
module is enabled by default, but can be disabled by specifying ``migrate:
false`` in config.

**Internal name:** ``cc_migrator``

**Module frequency:** always

**Supported distros:** all

**Config keys**::

    migrate: <true/false>
