Specifies the canary migration state. Possible values are PREPARE,
TEST_BY_PERCENTAGE, and TEST_ALL_TRAFFIC.
To begin the migration from EXTERNAL to EXTERNAL_MANAGED, the state
must be changed to PREPARE. The state must be changed to
TEST_ALL_TRAFFIC before the loadBalancingScheme can be changed to
EXTERNAL_MANAGED. Optionally, the TEST_BY_PERCENTAGE state can be
used to migrate traffic by percentage using
externalManagedMigrationTestingPercentage.
Rolling back a migration requires the states to be set in reverse
order. So changing the scheme from EXTERNAL_MANAGED to EXTERNAL
requires the state to be set to TEST_ALL_TRAFFIC at the same time.
Optionally, the TEST_BY_PERCENTAGE state can be used to migrate some
traffic back to EXTERNAL or PREPARE can be used to migrate all
traffic back to EXTERNAL.
