Teach git-notes about "notes.mergestrategy" to select a general strategy
for all notes merges. This enables a user to always get expected merge
strategy such as "cat_sort_uniq" without having to pass the "-s" option
manually.

This error message points the user at the source of the problem
("--strategy"). Good.

This error message doesn't. Perhaps it should mention the config
variable "notes.mergestrategy" to help the user track down the problem
more quickly?

Add new option "notes.<ref>.mergestrategy" option which specifies the merge
strategy for merging into a given notes ref. This option enables
selection of merge strategy for particular notes refs, rather than all
notes ref merges, as user may not want cat_sort_uniq for all refs, but
only some. Note that the <ref> is the local reference we are merging
into, not the remote ref we merged from. The assumption is that users
will mostly want to configure separate local ref merge strategies rather
than strategies depending on which remote ref they merge from. Also,
notes.<ref>.merge overrides the general behavior as it is more specific.
