[Search input] - [Suggested api changes while beta]

[tlabaj]

Is this a new component or an extension of an existing one?
Search Input

Describe the feature

1. SearchInput
   Change the order of the params in the following SearchInput props so event is first:

• onChange
• onSearch

2. ExpandableInput interface

• Rename to SearchInputExpandable so name is prepended with component name.
• Change the order of the params in onToggleExpand so event is first

3. Prepend component name to SearchAttribute so it would be SearchInputSearchAttribute

These changes should be made while beta.
