---------------------------------------
Submitted PR: https://github.com/apache/incubator-myriad/pull/19
Problem is that Optional<T> does not serialize correctly <T>. It shows state
"present" instead of value.
Created custom serializers to produce value if present and string "value is
absent" when value is absent.
> /api/config missing myriadExecutorConfiguration & nodeManagerConfiguration's
> param key value.

> When executed the /api/config to get myriad configs, the api output doesn't
> have values for nodeManagerConfiguration & myriadExecutorConfiguration's
> parameter keys.
> e.g. /api/config json (snippet) output:
> "myriadExecutorConfiguration": {
> "jvmMaxMemoryMB": {
> "present": true <----------
> },
> "nodeManagerUri": {
> "present": false <----------
> },
> "path":
> "file:///opt/mapr/myriad/myriad-0.1/lib/myriad-executor-runnable-0.0.1.jar"
> },
> "nativeLibrary": "/usr/local/lib/libmesos.so",
> "nmInstances": {
> "medium": 1
> },
> "nodeManagerConfiguration": {
> "cgroups": {
> "present": true <----------
> },
> "cpus": {
> "present": true <----------
> },
> "jvmMaxMemoryMB": {
> "present": true <----------
> },
> "jvmOpts": {
> "present": false <----------
> }
> },
> From myriad-config-default.yml:
> nodemanager:
> jvmMaxMemoryMB: 1024
> cpus: 0.2
> cgroups: false
> executor:
> jvmMaxMemoryMB: 256
> path:
> file:///opt/mapr/myriad/myriad-0.1/lib/myriad-executor-runnable-0.0.1.jar
> #The following should be used for a remotely distributed URI, hdfs assumed
> but other URI types valid.
> #nodeManagerUri: hdfs://namenode:port/dist/hadoop-2.5.0.tar.gz
> #path:
> file:///opt/mapr/myriad/myriad-0.1/lib/myriad-executor-runnable-0.0.1.jar
> As the parameter values are specified in *.yml, /api/config json output
> should contain the values for the param keys.
