For idwiki/viwiki, we wish to run the sticky header edit button AB
test so that treatment1 group sees the sticky header without edit
buttons, treatment2 groups sees the sticky header with edit buttons,
and the control/unsampled groups see no sticky header at all.
This patch overrides the configuration to make the sticky header
w/o edit buttons for treatment1, sticky header w/ edit buttons for
treatment2, and hides sticky header for everyone else. This depends
on a configuration with the treatment groups having "treatment1"
and "treatment2" as substrings in their bucket names.
The full configuration for idwiki/viwiki would be something like
the following:
```
$wgVectorStickyHeader = [
"logged_in" => true,
"logged_out" => false,
];
$wgVectorStickyHeaderEdit = [
"logged_in" => true,
"logged_out" => false,
];
$wgVectorWebABTestEnrollment = [
"name" => "vector.sticky_header_edit",
"enabled" => true,
"buckets" => [
"unsampled" => [
"samplingRate" => 0
],
"noStickyHeaderControl" => [
"samplingRate" => 0.34
],
"stickyHeaderNoEditButtonTreatment1" => [
"samplingRate" => 0.33
],
"stickyHeaderEditButtonTreatment2" => [
"samplingRate" => 0.33
]
],
];
```
