[pxetool] Please add an ability to sort the servers on a page with a location

[Andrey Nikitin]

Hello!

I'd like to ask you to add ability to sort the servers on a page with a location. For example, in case, when I want to add on the page with 'Czech' location a part of "new" servers, but at the same time I have a lot of "old" servers there. In this case, for example, when we are using 'srvXXX-bud' name in prefix, all new servers wil be added to the end of page. I should scroll down to edit a configuration of a server or to select the list of the servers to start deployemnt of them.

I want to have the ability to sort out the list of the servers on the following, for example, separated groups:
-- servers with errors on time of deploying (Error status);
-- servers are deployed without errors (Done status);
-- new servers (New status);
-- server with undefined status by any reasons (Unknown status);
-- servers on any status of deploying (installing, booting_to_os, configuring and so on).

This feature will make interface of pxetool more user-friendly.

Thanks in advance!
