-Add scheduler optimization options, short circuit all predicates if …
…one predicate fails
Signed-off-by: Wang Guoliang <iamwgliang@gmail.com>
**What this PR does / why we need it**:
Short circuit all predicates if one predicate fails.
I think we can add a switch to control it, maybe some scenes do not need to know all the causes of failure, but also can get a great performance improvement; if you need to fully understand the reasons for the failure, and accept the current performance requirements, can maintain the current logic. It should expose this switch to the user.

Allow scheduler set AlwaysCheckAllPredicates, short circuit all predicates if one predicate fails can greatly improve the scheduling performance.

- Remove string decode logic. It's not really helping to find the
conflict ports, and it's expensive to do encoding/decoding
- Not to parse the container ports information in predicate meta, use
straight []*v1.ContainerPort
- Use better data structure to search port conflict based on ip
addresses
- Collect scattered source code into common place
This moves plugin/pkg/scheduler to pkg/scheduler and
plugin/cmd/kube-scheduler to cmd/kube-scheduler.
Bulk of the work was done with gomvpkg, except for kube-scheduler main
package.
Balanced Resource Allocation policy can now be enabled to so that
host(s) with balanced resource usage would be preferred. The score
given by BRA also scales from 0 to 10 with 10 representing that the
resource usage is well balanced.
* Improper format specifier (e.g. %s for bools or %s for ints)
* More or less parameters than format specifiers
* Not calling a formatting function when it should have (e.g. Error() instead of Errorf())
