Description of problem:
 Default values for infinispan contain spaces. We should remove them as they are ignored anyway.

Version-Release number of selected component (if applicable):
 6.2.0.ER6

How reproducible:
 Always

Steps to Reproduce:
 1. Run gui installer, go to Post-install Configuration screen using default values.
 2. Select to install Infinispan Cache
 3. Observe values on Infinispan screen

Actual results:
Infinispan Name = "jboss eap"
JNDI Name = "java:jboss/infinispan/jboss eap"
Local Cache Name = "jboss eapCache"

Expected results:
Infinispan Name = "jbosseap"
JNDI Name = "java:jboss/infinispan/jbosseap"
Local Cache Name = "jbosseap-cache"

Additional info:
 - This should be fixed also for console installer
Current values passed by installer in CLI commands:
Infinispan Name = "jbosseap"
JNDI Name = "java:jboss/infinispan/jboss eap"
Local Cache Name = "jbosseapCache"

standalone.xml snipped using current default values:
<cache-container name="jbosseap" jndi-name="java:jboss/infinispan/jbosseap">
    <local-cache name="jbosseapCache">
        <transaction mode="NONE"/>
        <eviction strategy="NONE" max-entries="50000"/>
        <expiration max-idle="100000"/>
