dev-manual: add a hash equivalence server setup document

Add a small document to describe how to start a Hash Equivalence server
with bitbake-hashserv, the reference server provided by BitBake.

Update reference to hash equivalence in other places in the
documentation to mention this document.

Move the note from the concepts document to the new document, as a
warning note.

-   The shared Hash Equivalence server needs to be maintained together with the
-   Shared State cache. Otherwise, the server could report Shared State hashes
-   that only exist on specific clients.
-
-   We therefore recommend that one Hash Equivalence server be set up to
-   correspond with a given Shared State cache, and to start this server
-   in *read-only mode*, so that it doesn't store equivalences for
-   Shared State caches that are local to clients.
-
-   See the :term:`BB_HASHSERVE` reference for details about starting
-   a Hash Equivalence server.
+Setting up a Hash Equivalence server is described in the
+:doc:`/dev-manual/hashequivserver` section of the Yocto Project Development
+Tasks Manual.
