Store initial value for boolean selects in data-initial-value too

This was done in 02ceddb for other selects, but boolean ones were
forgotten.

Note that we need a handlebars helper to properly store "false". See

BNC#889444 Fix unsetting the applied proposal flag

On a fresh install, the proposals were marked as not having the latest
version applied. This was due to nodes being added to the proposal after
it was committed.

Keep the flag set when saving in add_role_to_instance_and_node.

Fix barclamp and name methods to work w/ networks

ProposalObject is (ab)used to also write data bags that contain network
information (and not proposals).

Commit 5614efd broke this because the regular expressions were not
matching at all.

This is only really visible when the network barclamp is applied, which
is usually on install.

Move crowbar_node_status tool from barclamp-crowbar to barclamp-nagios

This tool is talking to nagios, so should really live with
barclamp-nagios.
Support finding crowbar subcommands when the executable is a symlink

Right now, the crowbar tool only looks for subcommands in the current
directory and in the directory of the executable. We change the latter
to look for subcommand in the directory of the symlink target if the
executable is a symlink.

This allows having a /usr/bin/crowbar symlink pointing to
/opt/dell/bin/crowbar.

Read /etc/crowbar.install.key when CROWBAR_KEY env var is not set

There's no reason the tools cannot try to read the file when the
environment variable is not set.
