Public Autoconnect [API | Summary]

[mrpalide]

Did you run make format && make check? Yes

Fixes #904

Changes:

• Add public_autoconnect field to /visors/{pk}/summary endpoint
• Make new endpoint PUT /visors/{pk}/public-autoconnect to change value of public_autoconnect. The body of request should be same as {"public_autoconnect":true}.

How to test this PR:

• Check summary on network monitor to see public_autoconnect field.
• Make PUT request on /visors/{pk}/public-autoconnect endpoint with {"public_autoconnect":true} or {"public_autoconnect":false} to change its value.
• Check summary again for changes.

Note:
As I talked to @jdknives , after this changes we need restart/reboot visor to start connector routine. Maybe after successful change, we should show some alert/notification to user for reboot visor. @Senyoret1
