Appsody stack fails since #397 was merged

[NottyCode]

Describe the bug
When doing appsody run with a java-microprofile projectt created since #397 was merged you get this error:

[Container] [INFO] ------------------------------------------------------------------------
[Container] [INFO] BUILD SUCCESS
[Container] [INFO] ------------------------------------------------------------------------
[Container] [INFO] Total time:  4.569 s
[Container] [INFO] Finished at: 2019-10-07T21:31:56Z
[Container] [INFO] ------------------------------------------------------------------------
[Container] Should be a loose application:
[Container]   <configuration>
[Container]     <looseApplication>true</looseApplication>
[Container]   </configuration>
[Container] [Error] FATAL error APPSODY_PREP command received an error.  The controller is exiting: exit status 1
[Error] Error in 'appsody run': exit status 1

This is because validate.sh needs to have the following removed:

# Enforcing loose application
l_looseConfig=$(xmlstarlet sel -T -N x="http://maven.apache.org/POM/4.0.0" -t -v "/x:project/x:build/x:plugins/x:plugin[x:artifactId='liberty-maven-plugin']/x:configuration/x:looseApplication" pom.xml)
if ! [ "${l_looseConfig}" == "true" ]; then
  echo "Should be a loose application:
  <configuration>
    <looseApplication>true</looseApplication>
  </configuration>"
  exit 1
fi

To Reproduce
Steps to reproduce the behavior:

1. appsody init java-microprofile
2. appsody run

Expected behavior
Expect it to build without failure.

Apologies for this. This was not detected in our CI and clearly should not have been merged. We have reverted this PR and released a new functioning stack. Will work with @Emily-Jiang to submit an updated PR.
