partial_match does not support parenthesis () in object

[jadhaj]

During instance reconfigure, user is required to supply a new flavor
Navigate to instance details and them got to Configuration > Reconfigure this instance

The name of the flavor appears along with it;s properties like this:
m12.tiny (1 CPU, 0.0625 GB RAM, 3.0 GB Root Disk)

It seems that because parenthesis () are special characters, partial match is failing

So, view.form.flavor.fill('m12.tiny (1 CPU, 0.0625 GB RAM, 3.0 GB Root Disk)') is working
But: view.form.flavor.fill('m12.tiny') is not

We need the ability to partially match string with parenthesis ()
