correct corsAllowedOrigins in master config

[yithian]

Description

Update the installer to correct the regex it adds to the master config

Expected Behavior

The installer adds the correct regex to corsAllowedOrigins in the master config. The origin should be of this form: - (?i)//tutorial-web-app-webapp\\.{{ shard }}\\.{{ cluster }}\\.{{ domain }} \\.{{ tld }}(:|\\z).

Actual Behavior

The installer installs an incorrect regex to corsAllowedOrigins in the master config, or possibly doesn't install one at all. That part wasn't made clear to me.
