Use webview to show or follow component's log

[dgolovin]

Calling 'Follow/Show Log' command form OpenShift Application View creates new terminal every time. Cons of this approach are:

1. There is no way to close all/part of terminals with one operation
2. Showing long log in terminal takes time and cannot be canceled

Using special editor to show/follow log would solve all those problems.
