Clean Chrome browser installation.
##### SUMMARY
<!-- Explain the problem/feature briefly -->
There seems to be some kind of timing issue, when trying to establish a console connection to a VM using noVNC. Sometimes it does not try to connect. This behavior is really inconsistent between different devices, as trying to connect from some devices had no issue, while others never were able to connect. However we could narrow it down to some timing issue in the browser.
There is a point, where the noVNC connect button is clicked from Javascript (you can not click the button manually, as it is hidden). Depending on the environment this succeeded or not. The most issues seem to be caused by Firefox. But a fresh installation of Chrome shows a similar behavior. Interestingly you can somehow "fix" this issues, by installing arbitrary browser extensions (maybe they delay the page rendering just so slightly, that the connect button gets clicked). I recorded a Video demonstrating the behavior by enabling and disabling the "Google Translator" extension. Note, that this is a completely fresh installation of Chrome, with all default extensions disabled.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.

**Manually "clicking" connect via Javascript**

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
Connecting to the console actually connects to the console in every browser and environment.
##### ACTUAL RESULTS
<!-- What actually happened? -->
Depending on the environment, a connection to a VM console can be established or not.

@MoeRT09 I think we don't have nightly(publicly hosted) packages, can you try to build the packages yourself? Or wait until we do a 4.15.1.0 RC1 (sometimes in April).
I'm closing based on the discussions that the original issue has been fixed in https://github.com/apache/cloudstack/pull/4833

@weizhouapache you are right. Appending the `autoconnect=true` parameter to the URL of the iframe fixes it.
