ignore .idea folder in glance

[ling-yun]

If we use JetBrains PyCharm as python develop tool, JetBrains PyCharm would automatically generate its config folder name .idea in the root dir of your python code. Many Code projects, such as nova and cinder, have ignore .idea folder. Project glance should also ignore .idea folder.
