Some counters are maintained for each active alias. Currently, the following counters are supported: * inner_retries * outer_retries

counter() = atom()

counters() = #{counter() := integer()}

increment() = integer()

get/1	Fetches all known counters for `Alias`, in the form of a map, `#{Counter => Value}`.
get/2	Fetches the integer value of the known counter `Ctr` for `Alias`.
incr/3	Increment `Ctr` counter for Alias` with increment `N.
new/0

Fetches all known counters for Alias, in the form of a map, #{Counter => Value}.

get(Alias::alias() | db_ref(), Ctr::counter()) -> integer()

Fetches the integer value of the known counter Ctr for Alias.

incr(Alias::alias() | db_ref(), Ctr::counter(), N::increment()) -> ok

Increment Ctr counter for Alias` with increment `N.

Note that the first argument may also be a db_ref() map, corresponding to mrdb:get_ref({admin, Alias}).
