Fix several issues in sourcing AIGP attribute: 1) AIGP should not be set as default for a redistributed route or a static network. It should be set by config instead. 2) AIGP sourced by "set aigp-metric igp-metric" in a route-map does not set the correct value for a redistributed route. 3) When redistribute a connected route like loopback, the AGIP (with value 0) is sourced by "set aigp-metric igp-metric", but the attribute is not propagated as the attribute flag is not set.

Fix several issues in sourcing AIGP attribute:
AIGP should not be set as default for a redistributed route or a
static network. It should be set by config instead.
AIGP sourced by "set aigp-metric igp-metric" in a route-map does
not set the correct value for a redistributed route.
When redistribute a connected route like loopback, the AGIP (with
value 0) is sourced by "set aigp-metric igp-metric", but the
attribute is not propagated as the attribute flag is not set.
