Listing directory too slow

Hello.

I have total 373 files in my artifactory path, and below example code spend more than 3 seconds. 😭

```python
path = ArtifactoryPath("http://repo.jfrog.org/artifactory/distributions/org/")

for p in path.glob("**/*.gz"):
print(p)
```

But the official listing API returns immediately. (in a milli seconds)

Can you please improve the performance for the basic file listing call?

Start at the ArtifactoryPath("http://repo.jfrog.org/artifactory/distributions/org/") call and its glob("**/*.gz") entry point, then compare the current listing behavior with JFrog's official File List API. Done means the example returns the same matching paths without the reported multi-second delay.
