Update Centos Installation include dependencies
I attempted to follow the documentation to install HASS on to Centos 7.5 minimal. I found gcc gcc-c++ were required for hass to complete the auto install of various python packages and systemd-devel for zwave. Figure this information/step should be included in the installation wiki for centos.

To run Python 3.x on [CentOS](https://www.centos.org/) or RHEL (Red Hat Enterprise Linux), [Software Collections](https://www.softwarecollections.org/en/scls/rhscl/rh-python36/) needs to be activated first.
You must install Python 3.5.3 or later. Software Collections version of Python 3.5 is 3.5.1 so this guide uses Python 3.6.
### {% linkable_title Using Software Collections %}
First of all install the software collection repository as root. For example, on CentOS:
```bash
$ yum install centos-release-scl
```
Install some dependencies you'll need later.
```bash
$ yum install gcc gcc-c++ systemd-devel
```
Then install the Python 3.6 package:
```bash
$ yum install rh-python36
```
Once installed, switch to your `homeassistant` user (if you've set one up), enable the software collection and check that it has set up the new version of Python:
```bash
$ scl enable rh-python36 bash
$ python --version
Python 3.6.3
```
You will be in a command shell set up with Python 3.6 as your default version. The virtualenv and pip commands will be correct for this version, so you can now create a virtual environment and install Home Assistant following the main [instructions](/docs/installation/virtualenv/#step-4-set-up-the-virtualenv).
You will need to enable the software collection each time you log on before you activate your virtual environment.
### {% linkable_title Systemd with Software Collections %}
To autostart Home Assistant using systemd follow the main [instructions](/docs/autostart/systemd/) and adjust the template as follows:
```
[Unit]
Description=Home Assistant
After=network.target
[Service]
Type=simple
User=homeassistant
# Make sure the virtualenv Python binary is used
Environment=VIRTUAL_ENV="/srv/homeassistant"
Environment=PATH="$VIRTUAL_ENV/bin:$PATH"
# ExecStart using software collection:
ExecStart=/usr/bin/scl enable rh-python36 -- /srv/homeassistant/bin/hass -c "/home/homeassistant/.homeassistant"
[Install]
WantedBy=multi-user.target
```
