=head1 NAME
Munin::Master::Host - Holds information on hosts we are interested in
collecting data from.
=head1 DESCRIPTION
NOTE that a host and a node are not the same thing -- some hosts may
report services for several nodes, for example if they have SNMP plugins
installed.
=head1 METHODS
=over
=item B<new>
my $host = Munin::Master::Host->new($hostname, $group, \%attrs);
Constructor. C<$group> is the C<Munin::Master::Group> object this host
belongs to. Valid attributes include C<port>, C<update>, and
c<use_node_name>.
=item B<get_full_path>
Returns the full nested named path of the host object (eg. "group1;group2;hostname").
=item B<add_attributes_if_not_exists>
$host->add_attributes_if_not_exists(\%attrs);
Merges the new attributes from %attrs into the host object, without
overwriting any existing
=item B<get_canned_ds_config>
