This PR contains the minimum changes needed to stop inserting into the serial_numbers table. This is the first step in completely deprecating that table.
The next step is to create another PR to remove the expiredSerial chore, fix more tests, and remove any other methods on the serial_number table.

This fix issues with passing observers between iteration methods.
It's not best implementation but I think we will need to optimize it
soon one way or another.

The chief segment health models we've come up with are the "immediate
danger" model and the "survivability" model. The former calculates the
chance of losing a segment becoming lost in the next time period (using
the CDF of the binomial distribution to estimate the chance of x nodes
failing in that period), while the latter estimates the number of
iterations for which a segment can be expected to survive (using the
mean of the negative binomial distribution). The immediate danger model
was a promising one for comparing segment health across segments with
different RS parameters, as it is more precisely what we want to
prevent, but it turns out that practically all segments in production
have infinite health, as the chance of losing segments with any
reasonable estimate of node failure rate is smaller than DBL_EPSILON,
the smallest possible difference from 1.0 representable in a float64
(about 1e-16).
Leaving aside the wisdom of worrying about the repair of segments that
have less than a 1e-16 chance of being lost, we want to be extremely
conservative and proactive in our repair efforts, and the health of the
segments we have been repairing thus far also evaluates to infinity
under the immediate danger model. Thus, we find ourselves reaching for
an alternative.
Dr. Ben saves the day: the survivability model is a reasonably close
approximation of the immediate danger model, and even better, it is
far simpler to calculate and yields manageable values for real-world
segments. The downside to it is that it requires as input an estimate
of the total number of active nodes.
This change replaces the segment health calculation to use the
survivability model, and reinstates the call to SegmentHealth() where it
was reverted. It gets estimates for the total number of active nodes by
leveraging the reliability cache.

WHAT:
added brotli compression for wasm files and added copying of those files to static/wasm folder in Dockerfile
WHY:
those files are a part of web worker webpack bundle and I didn't find a way to compress them separately using webpack.
I'm open to any other ideas if they come up

Currently node id in access grant is '1' and it cannot be parsed to
valid node id. This change update access grant satellite address with
randomly generated node id.

A few weeks ago it was discovered that the segment health function
was not working as expected with production values. As a bandaid,
we decided to insert the number of healthy pieces into the segment
health column. This should have effectively reverted our means of
prioritizing repair to the previous implementation.
However, it turns out that the bandaid was placed into the code which
removes items from the irreparable db and inserts them into the repair
queue.
This change: insert number of healthy pieces into the repair queue in the
method, RemoteSegment

there were two changes to this package: one that modified
some things and renamed access.go to main.go, and one that
reduced the binary sizes against main.go.
somehow the latter change was included on this branch but
the former was not, which made the folder contain both
main.go and access.go. building the package then fails
with duplicate definitions.
the easiest fix is to remove access.go which makes the folder
match the contents of the current master branch.

There is a new checker field called statsCollector. This contains
a map of stats pointers where the key is a stringified redundancy
scheme. stats contains all tagged monkit metrics. These metrics exist
under the key name, "tagged_repair_stats", which is tagged with the
name of each metric and a corresponding rs scheme.
As the metainfo observer works on a segment, it checks statsCollector
for a stats corresponding to the segment's redundancy scheme. If one
doesn't exist, it is created and chained to the monkit scope. Now we can call
Observe, Inc, etc on the fields just like before, and they have tags!
durabilityStats has also been renamed to aggregateStats.
At the end of the metainfo loop, we insert the aggregateStats totals into the
corresponding stats fields for metric reporting.

Make changes so that we only import the necessary files from the console package so that the generated wasm code is as small as possible.
This change gets the compiled wasm code down to 8.6MB uncompressed and 2MB when compressed with `gzip --best`.
