Bug 973219

+++ This bug was initially created as a clone of Bug #970805 +++

Description of problem:
In the installation scripts and deployment guide, we do not change the ServerName setting for the broker's Apache from the default of 'localhost'.  Consequently, the TLS handshake raises a warning alert.  This warning alert can cause JBoss Developer Studio to report an authentication failure.

Version-Release number of selected component (if applicable):

How reproducible:
Thoroughly.

Steps to Reproduce:
1. Install a new broker host and a new node host using the installation scripts under <https://github.com/openshift/openshift-extras/blob/enterprise-1.1/enterprise/install-scripts/> (for OSE 1.1), the scripts under <https://github.com/openshift/openshift-extras/blob/enterprise-1.2/enterprise/install-scripts/> (for OSE 1.2), or the deployment guide at <https://access.redhat.com/site/documentation/en-US/OpenShift_Enterprise/1/html-single/Deployment_Guide/index.html>.

2. Run `httpd -S` on the broker host.

3. Run `tcpdump -lnni eth0 -w /tmp/tcpdump.out tcp port 443` on the broker host, run `curl -k https://broker.example.com/broker/rest/api` on a host that is remote to the broker, and run Wireshark on the resulting tcpdump.out file.

Actual results:

In Step 2, the `httpd -S` output shows 'localhost' for the virtual servers.

In Step 3, Wireshark shows "TLSv1    Alert (Level: Warning, Description: Unrecognized Name), Server Hello, Certificate" in the TLS handshake of every new connection.

Expected results:

In Step 2, the `httpd -S` output should show the configured hostnames for the virtual servers.

In Step 3, Wireshark should not show any warnings or errors in the TLS handshake.


Need to make the following Docs changes (based on the current 1.1 documentation):
Section 5.8.6.2 - Remove '-extensions v3_req' from the openssl command to generate a self signed cert.
Section 6.8.6.1 - Remove '-extensions v3_req' from the openssl command to generate a self signed cert.
Section 6.8.6.1 - Remove the duplicate line '-x509 -days 3650 -extensions v3_req \'

We also need to add a section to both the node and broker configuration to set the ServerName.
Node:
modify /etc/httpd/conf.d/000001_openshift_origin_node.conf
Change ServerName to hosts fqdn or run the following sed command
sed -i -e "s/ServerName .*$/ServerName `hostname`/" \
  /etc/httpd/conf.d/000001_openshift_origin_node.conf

Broker:
modify /etc/httpd/conf.d/000002_openshift_origin_broker_servername.conf
Change ServerName to hosts fqdn or run the following sed command
sed -i -e "s/ServerName .*$/ServerName `hostname`/" \
  /etc/httpd/conf.d/000002_openshift_origin_broker_servername.conf
