`st2web_package_name` is undefined

[mamercad]

After pinning st2web_version: 3.7.0-1, I get the following error:

    The task includes an option with an undefined variable. The error was: 'st2web_package_name' is undefined

    The error appears to be in '/Users/mmercado/src/[redacted]/ansible-st2/roles/StackStorm.st2web/tasks/main.yml': line 26, column 3, but may
    be elsewhere in the file depending on the exact syntax problem.

    The offending line appears to be:

    - name: Install pinned st2web package
      ^ here

Initially, I had it unset (so, presumably defaulted to stable). On my second run, I decided to pin the version and hit the error above.

You can specify the st2web_package_name in your top-level variables to get round this. But this really should be in role/st2web/defaults/main.yml and set to "st2web". Or event we probably don't need the variable anymore, as its a legacy from when we had st2web and st2flow.
