Unify log-manager log url

[Binyang2014]

Currently, to retrieve full log, we use the url:
https://master-address/log-manager/node_ip:9103/full/username/framework_uid/taskrole/pod_uid/user_log
This url is strange, we better to change it to:
https://master-address/log-manager/node_ip:9103/username/framework_uid/taskrole/pod_uid/user_log?content=full for better debug purpose. And will be unified with other log-manager urls.

We also need to change retrieve tail log url.
