When editing flavor extra spec, it's creating a new entry instead of updating the current one

[Gustavo Knüppe]

In Horizon, when editing a flavor extra spec, in case of you change the key name, horizon will not update the selected extra spec but create a new one.

STEPS TO REPRODUCE:
1. login on Horizon
2. select "admin" TAB
3. Select "Flavors" option
4. for a given flavor, click on "More" and select "View extra spec"
5. Create and extra expec with key "test1" value "value1"
6. in the created entry line, click on "edit" button
7. change key to "test2" and value "value2"

You' see a new entry will be created and both will be kept.

As a solution, the field that contain the "key" should not accept changes when editing extra spec.
This way only the value is updated properly and no new entry is created.

nova api can not update "key". I will remove the key field in edit dialog.

If any one want to update "key", he/she has to delete it and create a new one.

    Hide key field in edit Flavor Extra Specs dialog

    Nova allow user to add key/value to flavor, but its api is only
    able to update value according to key.

    Hide the key field in edit dialog, in order to avoid confusion.
    User can delete and create new one when need to update "key".
