when create task switch in python api, switch branch not show correctly,
due to we add some unnecessary attribute to switch task, this patch we
add `_task_ignore_attr` in class `Task` to ignore those unnecessary
attribute from `_task_default_attr`
(cherry picked from commit a86f4e2693)

* Add a tutorial about it
* Change tutorial doc and combine into traditional docs
* Add sphinx-inline-tab for better view
* revert not need change
* Correct python function indent
* Correct integration test
* [python] Task condition missing two downstream param

close: #7763
* Add getter and setter property condition_resulth in base task
After #7505 merged. we could use condition task type
but our dependent set in the wrong direction, all
the condition operators should be upstream of the
current task instead of downstream

Cause procedure parameter name need `method` instead of `sql`
we change it's name. And remove parameter `sql` from parent
class `Database`
