Allow free choice of different display name as per the custom variant

[dileepZion]

Background

• If it is an enhancement of an existing feature, describe which feature and how it works at the moment.
• Currently the V_APP_NAME as per the tool, works to change the Bundle name(Target name) and also the Bundle Display name.
  Hence it is not possible to use only V_APP_NAME or app_name as a parameter to switch to different names of the app.
  Currently when I have gone through the code, here is the below way to update the info.plist
  In XCConfigFactory, updateInfoPlist method has below code:

Bash("plutil", arguments: "-replace", "CFBundleName", "-string", "$(V_APP_NAME)", configFilePath),
Bash("plutil", arguments: "-replace", "CFBundleDisplayName", "-string", "$(V_APP_NAME)", configFilePath),
Bash("plutil", arguments: "-replace", "CFBundleExecutable", "-string", "$(V_APP_NAME)", configFilePath),

Solution

It is good if we only give the V_APP_NAME to CFBundleName and CFBundleExecutable and allow the user to change CFBundleDisplayName according to their own requirement. Like,
Dev -> APP_NAME_DEV
QA -> APP_NAME_QA
UAT -> APP_NAME_UAT

Thanks!
