Rename "osc_sdk" to "osc_cli"

[jerome-jutteau]

Hi, this issue topic is about renaming osc_sdk to osc_cli.

As I understand that osc-cli code can eventually be used as a python SDK, the actual situation has several drawbacks:

• Some users are confused as we also provide osc-sdk-python
• Installing osc-cli by typing pip3 install osc-sdk is confusing as users just want to install the cli.

What I suggest:

• Make a new major release to avoid user breakage
• Rename osc_sdk folder to osc_cli
• Publish new pip package named osc-cli
