Subject: image_type_tezi.bbclass: add OTA provisioning support

Add two items into image json file: ota_provisioning and
ota_credentials.

ota_provisioning would be set 'True' if SOTA_PACKED_CREDENTIALS is
being set, and ota_credentials would be set to the basename of
SOTA_PACKED_CREDENTIALS.

These two variables would be checked in Tezi installer to determine
whether OTA provisioning is needed.

This patch would not cause any functional change in Tezi installer
while SOTA_PACKED_CREDENTIALS is not set.
