note linux dependency in local getting-started-guide

While the linux dependency is obvious with a moment's thought, some
users (especially on *nix) might plow ahead before realizing their
system isn't supported. This adds a requirements section and points
users in the direction of guides more likely to work for them.

Make global http timeout longer than most operations

We have a few long running operations today (sync=true, watch) that
exceed the original default http.Server timeout.  We should set the
timeout to a high enough limit that more granular controls can be
implemented.
The default client poll interval is extremely long

Most operations complete much more quickly than 20s, and those that
do take longer are going to be fixed to make them take less time
