docs: Removing the use of NameVirtualHost from the apache examples

It's not used anymore. It's deprecated in fact: https://httpd.apache.org/docs/2.4/mod/core.html#namevirtualhost

Change-Id: I76999cfacc10a244024ee0cca66dda95a0169a67

docs: Added more spacing to the apache2 examples

They're easier to read and a bit less bloated.

docs: Switching to /srv/www to be more FHS 3.0 conformat

It's more modern and well supported to use /srv/www now in place of
/var/www.

ref: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s17.html

docs: Added user, group and display name in WSGI examples

This properly sets the user and group for the wsgi processes in the
examples; as well as adding a display name for easier identification.

docs: Replace apachectl for systemctl commands

It's safe to asume that all modern distros; supported by OpenStack, will
have systemd implemented. It's better to favor systemctl in those cases.

docs: Emphasis to file paths and command options

I've enclosed configuration options or parameters in interpreted text
quotes.

Also, I've enclosed fiel paths with inline literal quotes.

docs: Fixed wording used to indicate the restart of apache

Just a little commit to make it clearer of what we're gonna do.
