(cherry picked from commit 09425d5a5158c2d3fdad794411b3bbc4bba47b15)
* Update gateway.asciidoc
Added a note to clarify that, in cases where nodes in a cluster have different setting, the node that is the elected master takes precedence over anything else.
* Update gateway.asciidoc
Updated as per @bleskes's comments
Always use the LocalGateway* equivalents
We already check in the LocalGateway whether a node is a client node, or
is not master-eligible, and skip writing the state there. This allows us
to remove this code that was previously used only for tribe nodes (which
are not master eligible anyway and wouldn't write state) and in
tests (which can shake more bugs out)
The `recovery_after_time` tells the gateway to wait before starting recovery from disk. The goal here is to allow for more nodes to join the cluster and thus not start potentially unneeded replications. The `expectedNodes` setting (and friends) tells the gateway when it can start recovering even if the `recover_after_time` has not yet elapsed. However, `expectedNodes` is useless if one doesn't set `recovery_after_time`. This commit changes that by setting a sensible default of 5m for `recover_after_time` *if* a `expectedNodes` setting is present.
