FreeBSD: improvements and fixes for use on Azure

This patch targets to make FreeBSD 10.3 or 11 work on Azure. The
modifications abide by the rule of:
  * making as less modification as possible
  * delegate to the distro or datasource where possible.

The main modifications are:
 1. network configuration improvements, and movement into distro path.
 2. Fix setting of password.
    Password setting through "pw" can only work through pipe.
 3. Add 'root:wheel' to syslog_fix_perms field.
 4. Support resizing default file system (ufs)
 5. copy cloud.cfg for freebsd to /etc/cloud/cloud.cfg rather than
    /usr/local/etc/cloud/cloud.cfg.
 6. Azure specific changes:
    a. When reading the azure endpoint, search in a different path
       and read a different option name (option-245 vs. unknown-245).
        so, the lease file path should be generated according to platform.
    b. adjust the handling of ephemeral mounts for ufs filesystem and
       for finding the ephemeral device.
    c. fix mounting of cdrom
