Improve logging for remote dev module
What does this MR do
- removed logging of the entire response received from Rails. Instead, payload size in bytes and no. of workspace data is logged
- added logging for requestId & duration of API call
The count of Info logs has not been changed as this is a trend across other modules as well. This can be addressed in the future if something merits this change
Relevant issue: gitlab-org/gitlab#409131 (closed)
