Problem: Custom compute offering does not allow setting min and max values for CPU and VRAM for custom VMs.
Root Cause: Custom compute offerings cannot be created with a given range of CPU number and memory instead it allows only fixed values.
Solution: createServiceOffering API has been modified to allow setting a defined range for CPU number and memory. Also, UI form for compute offering creation is provided with a new field named 'compute offering type’ with values - Fixed, Custom Constrained, Custom Constrained. It will allow the creation of compute offerings either with a fixed CPU speed and memory for fixed compute offering, or with a range of CPU number and memory for custom constrained compute offering or without predefined CPU number, CPU speed and memory for custom unconstrained compute offering.
To allow the user to set CPU number, CPU speed and memory during VM deployment, UI form for VM deployment has been modified to provide controls to change these values. These controls are depicted in screenshots below for custom constrained and custom unconstrained compute offering types.
Sample API calls using cmk to create a constrained service offering and deploying a VM using it,
create serviceoffering name=Constrained displaytext=Constrained customized=true mincpunumber=2 maxcpunumber=4 cpuspeed=400 minmemory=256 maxmemory=1024
deploy virtualmachine displayname=ConstrainedVM serviceofferingid=60f3e500-6559-40b2-9a61-2192891c2bd6 templateid=8e0f4a3e-601b-11e9-9df4-a0afbd4a2d60 zoneid=9612a0c6-ed28-4fae-9a48-6eb207af29e3 details[0].cpuNumber=3 details[0].memory=800

* feature: add libvirt / qemu io bursting
Adds the ability to set bursting features from libvirt / qemu
This allows you to utilize the iops and bytes temporary "burst" mode
introduced with libvirt 2.4 and improved upon with libvirt 2.6.

* updates per rafael et al
These boolean-return methods are named as "getXXX".
Other boolean-return methods are named as "isXXX".
Considering there methods will return boolean values, it should be more clear and consistent to rename them as "isXXX".
(rebase #2602 and #2816)
These Boolean-return methods are named "getXXX", but other Boolean-return methods are named "isXXX", such as the following two methods. They will return boolean values, rename them as "isXXX" should be more clear than "getXXX".
* CLOUDSTACK-10359: Change the inconsistent method names.
The two methods are named "getXXX".
The two method are checking the status of variables.
"getCustomized" is not as intuitive as "isCustomized".
"getIsSystem" is not as intuitive as "isSystem" as well.
* Add the missing changes of all usages of method getIsSystem.
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
