Allow min_l3_agents_per_router to equal one
As an operator, when I am running a setup with two network nodes, the
idea of running L3 HA is that an outage of one of the network nodes
should have minimum customer impact. With the current rules in place,
existing setups will indeed have little to no impact, but customers will
not be able to create new routers during the outage.
With this chance in place, we can set min_l3_agents_per_router=1, so the
customers will be affected even less. New routers will be created with
just one instance, which certainly is not optimal, but at least will
fulfill the customer request. Once the second network node recovers, the
second router instance will be added and thus redundancy restored.
Also change the help text to specify the effect of setting
min_l3_agents_per_router more clearly.

Title:
Neutron HA should allow min_l3_agents_per_router to equal one
Status in neutron:
Fix Released
Bug description:
As an operator, when I am running a setup with two network nodes, the
idea of running L3 HA is that an outage of one of the network nodes
should have minimum customer impact. With the current code, existing
setups will indeed have little to no impact, but customers will not be
able to create new routers during the outage.
If neutron would allow to set min_l3_agents_per_router=1, new routers
will be created even when just one agent is available, which certainly
is not optimal, but at least will fulfill the customer request. Once
the second network node recovers, the second router instance will be
added and thus redundancy restored.
