Impact: Fix the parsing issue when two or more values are specified

This patch fixes an issue where when two or more values are specified for
the controllers, only the last one is applied. This patch fixes that issue.
The parser is modified to collate all the name value pairs, seperated by
":". The reason for implementing it this way is because we need to pass
the controller name and splitting the rules would make it very hard to pass
the controller name to each rule, irrespective of where the controller name
was parsed.

Tested with the following config file

group default {
	perm {
		task {
			uid = root;
			gid = root;
		}
		admin {
			uid = root;
			gid = root;
		}
	}

	cpu {
		cpu.shares = 2048;
	}

	cpuset {
		cpuset.mems=0;
		cpuset.cpus=0-1;
	}
}

mount {
	cpu = /cgroup/cpu;
	cpuacct = /cgroup/cpu;
	cpuset = /cgroup/cpu;
}
