Fix conflicting key with kubespawner

[Ph0tonic]

https://github.com/jupyterhub/kubespawner 6.x is conflicting with this project. Version 6 now includes a way of configuring profiles a bit like wrapspawner but limited to kubernetes.
When they introduced this feature, they used the same key to get the right profile from the form. When trying to spawn a process with kubespawner from wrapspawner, it crashes with the following error:

This PR fixes this conflict by using a different key name, wrap_profile. I am currently using this fix in production and it's now working fine.

Hi, just willing to bump this up @mbmilligan 👍

Hello, any feedback on this issue ? This issue is really blocking any use with KubeSpawner.

Sorry for the slow response. Changing this key is a breaking change, since launch API calls may use this. Perhaps the right fix is to not pass consumed user_options field(s) to the child spawner? Or namespace them upon passing?

No problem, thank you very much for your feedback. I understand the need to avoid breaking changes but I am wondering whether the cost to avoid this situation is higher thank just releasing a 2.x version. Namespacing and filtering options could add some code not required making it more complicating to maintain. I am also not sure whether not passing consumed fields or namespacing them could also be considered a breaking change in itself as we change the list of arguments provided to spawners ?
