Having local variables gives false impression that this is overwritten
in the function block.

From API call WithRange and WithPrefix work the same, they just set the range end.
The difference is when the range end is provided:
* WithRange(end) requires providing the end while calling
* WithPrefix() calculates the end based on key provided to the Get.
For example, those are equal:
* client.Get(ctx, "/pods/", WithPrefix())
* client.Get(ctx, "/pods/", WithRange(GetPrfixRangeEnd("/pods/")))
As keyPrefix is equal preparedKey there should not be a difference.

returnRV was was equal to withRev, but updated at different time.
When preparing the request they are set equal to each other.
The only difference was during the for loop.
returnRV was always set no matter if pagination was enabled, while withRev only when paginating.

Mutex locking avoids the data race. Whether this variable really can be used
safely by those concurrent (?) tests is a different question...

Fix a segfault when collecting the storage size metrics when the getters
used to collect the data on etcd haven't been initialized properly. This
happens when the EtcdOptions are not applied which is the case for
aggregated apiservers that don't care about storage.

Instead of numerating all the etcd endpoints known by apiserver, we will
group them by purpose. `etcd-0` will be the default etcd, `etcd-1` will
be the first resource override, `etcd-2` will be the second override and
so on.

Change name to make it compliant with prometheus guidelines.
Calculate it on demand instead of periodic to comply with prometheus standards.
Replace "endpoint" with "server" label to make it semantically consistent with storage factory
