Add timeout parameter to cat api

[ppf2]

The nodes cat api appears to not have a timeout by default (and certainly not a way to set one). This suggests that it will wait forever on all the nodes to respond and may seem to hang. This is a request to add a timeout parameter.

@ppf2 If nodes are not responding, then they will be disconnected, and then the request will return. Why does this API in particular need a specific timeout parameter, as opposed to just having a timeout on the client side?

The will indeed return once the nodes are disconnected by the master. The nodes may also recover or just take long to answer. I think the idea is to add an (optional) timeout parameter that acts on the node level - I.e., you will get a response for all the nodes that did respond instead of a global timeout with no answer at all. These cat commands are sometimes used when the cluster is under pressure and you rather have partial information.

Specifically add it to cat-nodes, cat-indices and cat-recovery, which are broadcast to all nodes. Need to add a timeout column and an exception message column?
