tests: functional: Remove implicit and explicit wait times
- Splinter/selenium have implicit and explicit waiting time. Implicit wait time
will make every negative lookup wait for about 3 seconds before it actually
fails. Because we ensure missing elements in quite a few places, this introduces
many 3 seconds wait periods during testing. Remove it instead rely on explicit
waiting whenever needed.

- Explicit wait time is only used during explicitly requests waiting conditions.
In a loop the API waits for a maximum of timeout period until a given condition
is satisfied. Each time the condition is checked, it goes into sleep for
explicit wait period amount of time. This is typically a second or so. Since we
are impatient, make it 0.1 instead.

- Also make sure that whenever a page is visit()ed, we automatically wait until
the page is fully loaded by overriding the splinter wait condition. Otherwise,
we will need to introduce waiting code in a lot of places.

- Using document.readyState == complete is a better check to ensure that a page
is fully loaded. If we proceed with the page 'loading' or 'interactive' state,
we will have to change a lot of code to make it wait.

- Handle Apache restarts when waiting for page load. The error page apparently
is never reaches document.readyState == 'complete'. So, if an error page is
encountered, always reload.

- While waiting for installation, ensure that we atomically check that page has
loaded fully and the installation progress is not being shown. Otherwise, there
would be race condition due to installation page refreshing itself.
