Return string instead of an integer for the aggregate id in the aggregates extension

[Matthew Treinish]

In the next API version the aggregates id should be a string instead of an integer.

[Jim Jiang (jiangwt100)]

Should I change the aggregate_id type in nova api or nova compute or nova db ?

[Jiajun Liu (ljjjustin)]

I looked at the code, I think this problem is quite common, not just in aggregate extension. We should discuss this in mail list first.

This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on. If you decide to work on this
consider using a blueprint [1] (with spec [2]). I'll recommend to
read [3] if not yet done.

If there are any questions left, feel free to contact me (markus_z)
in the IRC channel #openstack-nova
