Add ability for users to filter Job Executions by exec id, status, or name

[cppwfs]

Epic spring-cloud/spring-cloud-dataflow#3866 shows how a user would like filter job executions via the UI. The server currently supports the following restful endpoints to provide the filtering requested:

    "jobs/executions/name": {
      "href": "http://localhost:9393/jobs/executions{?name}",
      "templated": true
    },
    "jobs/executions/status": {
      "href": "http://localhost:9393/jobs/executions{?status}",
      "templated": true
    },
    "jobs/executions/execution": {
      "href": "http://localhost:9393/jobs/executions/{id}",
      "templated": true
    },

We probably want @sabbyanandan 's input if we want to add these filters now or wait till stories 4164, 4165 and 4166 are completed so we can add all of the filters to the UI in one PR.
