This PR adds outputting human readable byte sizes in the management server logs, agent logs, and usage records. A non-dynamic global variable is added (display.human.readable.sizes) to control switching this feature on and off. This setting is sent to the agent on connection and is only read from the database when the management server is started up. The setting is kept in memory by the use of a static field on the NumbersUtil class and is available throughout the codebase.
Instead of seeing things like:
2020-07-23 15:31:58,593 DEBUG [c.c.a.t.Request] (AgentManager-Handler-12:null) (logid:) Seq 8-1863645820801253428: Processing: { Ans: , MgmtId: 52238089807, via: 8, Ver: v1, Flags: 10, [{"com.cloud.agent.api.NetworkUsageAnswer":{"routerName":"r-224-VM","bytesSent":"106496","bytesReceived":"0","result":"true","details":"","wait":"0",}}] }
The KB MB and GB values will be printed out:

Ceph used to use port 6789 (no need to specify it), but with the messenger v2
from Ceph it switched to port 3300 while 6789 still works.
librados/librbd/libvirt will automatically figure out the ports to use if none is
specified.
Therefor there is no need for CloudStack to explicitely define the port in the XML
passed to Libvirt or Qemu.
Leave blank if no port number has been defined by the user.

autocomplete)
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration
- remove custom <build> configuration in pom.xml
