able to acquire a read lock until the initial read lock is released.

at the first iteration, only the following metrics are collected:
- HTTP metrics of each API endpoint
- cache counter for request/hit/miss
- histogram of storage actions, including:
GetContent, PutContent, Stat, List, Move, and Delete

This adds a configuration setting `HTTP.TLS.LetsEncrypt.Hosts` which can
be set to a list of hosts that the registry will whitelist for retrieving
certificates from Let's Encrypt. HTTPS connections with SNI hostnames
that are not whitelisted will be closed with an "unknown host" error.
It is required to avoid lots of unsuccessful registrations attempts that
are triggered by malicious clients connecting with bogus SNI hostnames.
NOTE: Due to a bug in the deprecated vendored rsc.io/letsencrypt library
clearing the host list requires deleting or editing of the cachefile to
reset the hosts list to null.

This removes the old global walk function, and changes all
the code to use the per-driver walk functions.

This changes the Walk Method used for catalog enumeration. Just to show
how much an effect this has on our s3 storage:
Original:
List calls: 6839
real 3m16.636s
user 0m0.000s
sys 0m0.016s
New:
ListObjectsV2 Calls: 1805
real 0m49.970s
user 0m0.008s
sys 0m0.000s
This is because it no longer performs a list and stat per item, and instead
is able to use the metadata gained from the list as a replacement to stat.

Move the Walk types into registry/storage/driver, and add a Walk method to each
storage driver. Although this is yet another API to implement, there is a fall
back implementation that relies on List and Stat. For some filesystems this is
very slow.
Also, this WalkDir Method conforms better do a traditional WalkDir (a la filepath).
This change is in preparation for refactoring.
