Post introduction of parameterized tests we were getting unresolved parent pom error.

[ERROR] The project com.*.*.*.*:*-*:3.3.0-SNAPSHOT 
    (/Volumes/WorkSpace/*/*/*/*/pom.xml) has 1 error [ERROR] 
    Non-resolvable parent POM for com.ebay.ejmask:ejmask-bom:${revision}${changelist}: T
    he following artifacts could not be resolved: com.ebay.ejmask:ejmask-parent:pom:${revision}${changelist} 
    (absent): Could not transfer artifact com.ebay.ejmask:ejmask-parent:pom:${revision}${changelist} from/to * (https://*.*.*.com/content/repositories/v3debt/):
     status code: 401, reason phrase: Unauthorized (401) @ com.ebay.ejmask:ejmask-bom:${revision}${changelist},
      /Volumes/WorkSpace/*/maven/m2/*/com/ebay/ejmask/ejmask-bom/1.2.0/ejmask-bom-1.2.0.pom, line 4, column 13 -> [Help 2] [ERROR]

Proposed Changes

To avoid issues caused by variables in parent pom we introduced maven pom flattener
