EAM API: remove appid from appinstance path

[gainsley]

What type of PR is this?

• enhancement/feature

What this PR does / why we need it:

Removes appId from the appinstances path. For retrieval, it becomes an optional parameter, allowing a single API call to get appinstances from different Apps. For delete, it is not necessary because appInstanceId is sufficient to identify the instance.

Which issue(s) this PR fixes:

Fixes #299

Hi @gainsley , one thing about this: for the get and the delete method, looks good to me, but I have doubts about the post method, because if we make appId as optional how do we know which App is going to be instantiate?? If we don't add the appId on the requested body, could we instantiate all the Apps by mistake,??

Hi @JoseMConde thank you for catching that, indeed my change made the appId and appZone optional which is wrong. I've added the required spec so that they are required. Thanks for reviewing!
