Add --local option to load-import

Currently, load-import uploads .iso and .sig to sysinv-api, which
may be a very slow operation that may cause sysinv-api timeouts,
specially with larger iso sizes.

This commit adds a new --local option that instructs the client
to bypass the step that transfers the load via sysinv-api, instead
sending the .iso and .sig absolute paths on the active controller
filesystem so that conductor uses this information to import the
load locally.

Test Plan
PASS: import the load with --local option and verify:
      - Load information is populated on /var/www/pages/feed
      - Load is updated on the database to importing -> imported
PASS: import the load with --local option passing an invalid file
      format and verify:
      - load-import returns "signature could not be verified" error
      - Conductor logs "signature could not be verified" error
PASS: import the load with --local option passing an invalid file
      path and verify:
      - load-import returns "file not found" error
PASS: import the load with --local option and upgrade AIO-DX
PASS: import the load with --local option on systemcontroller
      and verify load uploaded to /var/www/pages/feed and
      /opt/dc-vault/loads

Regression
PASS: import the load without --local option and verify:
      - Load information is populated on /var/www/pages/feed
      - Load is updated on the database to importing -> imported
PASS: import the load without --local option passing an invalid file
      format and verify:
      - load-import returns "signature could not be verified" error
      - Conductor logs "signature could not be verified" error
PASS: import the load without --local option passing an invalid file
      path and verify:
      - load-import returns "file not found" error
