CLOUDSTACK-1065: cloudstack UI - AWS Style Regions - when switching region, set location without parameters.
1) fix CLOUDSTACK-1946 2) remove redundant VMSnapshotVO.java
Changing the number of threads in the test from 1000 to 750. 1000 will more often than not result in build failures due to constraints on the build systems.

Most recent centos based systems have process limit of 1024. Running this test will result in an OutOfMemory exception with description unable to create native thread.
CLOUDSTACK-1065: cloudstack UI - AWS Style Regions - shorten value of g_loginCmdText
CLOUDSTACK-1957: cloudstack UI - fix a JS error "'logout' is undefined" which sometimes shows on login screen.
Replace restart with SIGHUP

This signal will force the dnsmasq daemon to reload the configuration directly. This is much faster than restarting the daemon, which result in a much smaller window during which no dns server is available.

Tested by using the replaced version of edithosts.sh on a running vrouter causing dns problems.
Switching netscaler to the maven location of the
netscaler.nitro jar.

If it's there we might as well use it.

This fixes build problems for people with old netscaler jars as the
version was not updated in the jar.
CLOUDSTACK-1935: Rename tools from cloud-* to cloudstack-*
Continuing work on release notes.
Removing a few stray characters.
added minor issues to known issues.
