Remove dependency in swoole/openswoole extension for some options

[acelaya]

Some of the options are skipped if swoole extension is not detected. This is because, traditionally, they were relevant only for real-time updates, which used to require swoole.

Some versions ago, Shlink started to support roadrunner, which also supports real time updates. Someone trying to run Shlink with roadrunner and configured via installer tool would not get asked about some relevant questions.

Make those options stop depending on the presence of swoole/openswoole extension, and instead ask at the beginning how is Shlink going to be served, adjusting the questions accordingly.
