Hostmanager ASCII-Art Notice is furthermore not required

@jtreminio this was the change after using vagrant plugin hostmanager and we don't need to inform users through this `hostmanager-notice.txt` file in ascii-art directory because this plugin is already informing. Look this output.

```shell
$ vagrant up --no-provision

============================================================
You have the Vagrant::HostManager plugin installed.
You may be required to enter your host's root/privileged
password below to continue!
============================================================

==> default: Updating /etc/hosts file on host machine (password may be required)...

==> default: Machine not provisioning because `--no-provision` is specified.
```

AND really we don't require below ascii-art snippet in shell

```shell
============================================================
You have the Vagrant::HostManager plugin installed.
You may be required to enter your host's root/privileged
password below to continue!
============================================================
```
As `vagrant-hostmanager` plugin is informing in this smartly managed two lines... have a look 
```shell
==> default: Updating /etc/hosts file on active guest machines...
==> default: Updating /etc/hosts file on host machine (password may be required)...
```

What it doesn't deserve is that in provisioning it is displayed too?

```shell
$ vagrant provision

============================================================
You have the Vagrant::HostManager plugin installed.
You may be required to enter your host's root/privileged
password below to continue!
============================================================
