Fixed missing HTTP debug logging on VIM requests

When the sw-manager CLI ported some HTTP calls from urllib to requests
the debug logging capability was lost.

This change remedies this.

TEST PLAN
PASS: sw-manager ... commands work with no impact
PASS: sw-manager --debug ... work with no impact
  * Requests to VIM should be seen: send: b'POST
    /api/orchestration/sw-upgrade/strategy ...
  * Other debug logging still present:
    send: b'POST /v3/auth/tokens ...
