NamedServerFilter: Add HINT_ROUTE_TO_ALL support

Browse Source 
This was already supported by HintRouter. The tag for the MaxScale
config file is "->all". Also add note to Documentation and reformat
it a bit.

This is the hint which will be attached to the queries matching the regex. If a
compatible router is used in the service the query will be routed accordingly.
The target can be a server name, a list of server names (comma-separated),
`->master` or `->slave`. The server names add the names as hints (one name per
hint). `->master` adds a *route-to-master*- hint and `->slave` adds a
*route-to-slave*-hint.
The target can be one of the following:
* a server name (adds a `HINT_ROUTE_TO_NAMED_SERVER` hint)
* a list of server names, comma-separated (adds several
`HINT_ROUTE_TO_NAMED_SERVER` hints)
* `->master` (adds a `HINT_ROUTE_TO_MASTER` hint)
* `->slave` (adds a `HINT_ROUTE_TO_SLAVE` hint)
* `->all` (adds a `HINT_ROUTE_TO_ALL` hint)
