Issues in Management APIs
**Description:**
1. The transport values in data-services are missing GET data-services from the management api.
2. The sequence name is missing in response form GET sequence from the management api
3. If there is a de-active proxy service, an AxisFault is thrown when retrieving data-services
4. Missing fields such as default values in endpoint configurations

**Suggested Labels:**
<!-- Optional comma separated list of suggested labels. Non committers can’t assign labels to issues, so this will help issue creators who are not a committer to suggest possible labels-->

**Suggested Assignees:**
<!--Optional comma separated list of suggested team members who should attend the issue. Non committers can’t assign issues to assignees, so this will help issue creators who are not a committer to suggest possible assignees-->

**Affected Product Version:**

**OS, DB, other environment details and versions:**    

**Steps to reproduce:**

**Data-services**

1. Deploy a data service with transports.
`<data name="Accout_dataservice" serviceNamespace="http://ws.wso2.org/dataservice" serviceGroup="" transports="http https local">`

2. The values for transport property is getting missed at the response of the Management API as below.
`<data name=\\"Accout_dataservice\\" serviceNamespace=\\"http://ws.wso2.org/dataservice\\" description=\\"\\" enableBatchRequests=\\"false\\" enableBoxcarring=\\"false\\" disableLegacyBoxcarringMode=\\"false\\" transports=\\"\\">`

3. Deploy a proxy and deactivate the proxy service. (You can use MI dashboard). An AxisFault is thrown when retrieving data-services.

**Sequences**

1. Create a sequnces and deploy.
2. Invoke the get sequence request using the management api. The name of the sequence is missing in the configuration.
