Enable sticky sessions for HTTP targets

Network load balancers that forward to target groups registering more
than one target need to have sticky session enabled.

This ensures that all requests from the user during the session are sent
to the same target.

Currently network load balancers are used across the board, so the only
available stickiness type is based on client IP address. This can be
changed for HTTP requests when the load balancers are updated to be
Application Load Balancers.

There are only two target groups that register multiple targets, the
replica and the primaries gerrit target groups, so stickiness has
been enabled for those only.
