Subject [jira] [Commented] (CLOUDSTACK-5843) registering templates/isos should be either async or changed to non-blocking

Commit effa4c75b4970c1d87b2d1b0d83ae1f5e8312b0b in branch refs/heads/master from [~mlsorensen]

CLOUDSTACK-5843
For some reason the mgmt server is required to have access to the template
being registered in order to check its size against resource limits
during registration. This is bad, but worse, it's a sync call, so this
call can hang for up to the default HTTP connection timeout.

Reducing http timeout as a quick workaround, but this check needs to
1) be removed or 2) done later or 3)registerTemplate needs to be async
and 4) moved off the mgmt server (ssvm is the only thing that needs access to
template url).

> The call to register templates and isos does more than most sync calls do, it seems to
talk to the ssvm and have it run commands that can potentially time out. I ran into this in
a test system when we tried to register a template with a non-routable URL. The cloudstack
API call just hung. I realize that there was a problem (ssvm could not reach the template
host), but no sync call should do anything like this that would block.
