refactor(yurt-iot-dock): temporarily remove v3 client to deal with code duplication

[LavenderQAQ]

What type of PR is this?

/kind enhancement
/sig iot

What this PR does / why we need it:

For this pr, the client implementations of the yurt iot-dock of v2 and v3 are merged. Currently, the only difference between v2 and v3 clients is the api request path, which leads to a lot of code redundancy, so we won't separate them for now in 1.4. In 1.5 we will consider splitting them and bringing a MessageBus-based client implementation to v3.
Refer: #1680
