[Minor] Remove sequential algorithm as it is not actually a rotation alg
Sequential rotation was used just to rotate all upstreams in the loop (e.g.
when you need to do some action for all upstreams). Allowing to specify it as
a user defined algorithm was a mistake as it breaks upstreams API expectations.

[Fix] Fix consistent hashing when upstreams are marked inactive
The idea is to rehash the value when we found that the current upstream is dead
and apply consistent hashing algorithm multiple times. This is limited by
number of attempts (we try 10 times before giving up). Also cleanup locking
stuff.

[Fix] Core: Fix address rotation bug
Previously, upstream.get_addr function returned the new address of the
upstream. Unfortunately, it was used for printing addresses. It caused
the following situation: let's imagine we have A1 and A2 where A1 was
initially selected. So the connection was performed to A1:
Current addr Selected addr
Connect+---------+ A2+------>A1 A1
|
+-+Print failure<---+ A1+------>A2 A2
| +----+
+->Mark failure+-------->+ A2 |
+----+
But the failure OP as well as log message told about `A2` where the real
problem happened with `A1`.
This commit adds distinguishing between getting the next and the current
address of the upstream resolving this issue.
