FR: Option to append host aliases on a single line instead of every alias in its own line

[danowar2k]

I'm not sure if the current method can lead to bad behaviour.

Currently, using the aliases option...

Vagrantfile:

vm_config.vm.hostname = some-hostname
vm_config.hostmanager.aliases = %W(some-hostname.some-domain some-other-alias)

leads to the following lines (concrete IP not important):

1.2.3.4 some-hostname
1.2.3.4 some-hostname.some-domain
1.2.3.4 some-other-alias

I don't know if the resolving process will get problems with this, but I've heard that the stuff should be on the same line for an IP. Like this:

1.2.3.4 some-hostname some-hostname.some-domain some-other-alias

How about at least an option with which to select which way will be used?

It looks like if the option is defined, it would only be need to be used here:

vagrant-hostmanager/lib/vagrant-hostmanager/hosts_file/updater.rb

Line 104 in fe00b37

"#{ip}\t#{host}\n" + aliases.map{|a| "#{ip}\t#{a}"}.join("\n") + "\n"

To decide whether to do newlines for each alias or not (and whether to prefix the entry with IP, okay, it's a little more complex to build the string)
