Update github.com/google/certificate-transparency-go from v1.1.6 to
v1.3.1. This updates the loglist file schema to recognize logs which are
tagged as being tiled logs / implementing the static CT API.
Transitively update:
- github.com/go-sql-driver/mysql from v1.7.1 to v1.8.1
- github.com/prometheus/client_golang from v1.15.1 to v1.22.0
- github.com/prometheus/client_model from v0.4.0 to v0.6.1
- go.opentelemetry.io/otel from v1.30.0 to v1.31.0
- google.golang.org/grpc from v1.66.1 to v1.69.4
- google.golang.org/protobuf from v1.34.2 to v1.36.5
- and a variety of indirect dependencies
Remove one indirect dependency:
- github.com/matttproud/golang_protobuf_extensions
Add two new indirect dependencies:
- filippo.io/edwards25519@v1.1.0 (used by go-sql-driver to handle
mariadb's custom encryption implementation)
- github.com/munnerz/goautoneg@v0.0.0-20191010083416-a7dc8b61c822
(previously inlined into prometheus/common)
Also fix two unit tests which need minor modifications to work with
updated type signatures and behavior.

The `go` directive inside go.mod determines certain behaviors of
the go command. Since we're using go 1.17 everywhere, we should
update our module's go directive to reflect that, and update its contents
to match the new behavior.
Particularly, updating to 1.17 here means that all indirect dependencies
are listed directly inside go.mod (in a separate block, to keep things clean),
and the go.sum and go.mod files are deleted from vendored dependencies
so that the go tool can correctly find the root of the module even when run
from a vendored dependency's subdirectory.
* cmd: update prometheus.NewProcessCollector args.
There's a new struct `prometheus.ProcessCollectorOpts` that is expected
to be used as the sole argument to `prometheus.NewProcessCollector`. We
don't need to specify `os.Getpid` as the `PidFn` of the struct because
the default is to assume `os.Getpid`. Similarly we don't need to set the
namespace to `""` explicitly, it is the default.
* SA: reimplement db metrics as custom collector.
The modern Prometheus golang API supports translating between legacy
metric sources on the fly with a custom collector. We can use this
approach to collect the metrics from `gorp.DbMap`'s via the `sql.DB`
type's `Stats` function and the returned `sql.DbStats` struct.
This is a cleaner solution overall (we can lose the DB metrics updating
go routine) and it avoids the need to use the now-removed `Set` method
of the `prometheus.Counter` type.
* test: Update CountHistogramSamples.
The `With` function of `prometheus.HistogramVec` types we tend to use as
the argument to `test.CountHistogramSamples` changed to return
a `prometheus.Observer`. Since we only use this function in test
contexts, and only with things that cast back to
a `prometheus.Histogram` we take that approach to fix the problem
without updating call-sites.
This vendors the Prometheus client code, and exports metrics on the debug port, under `/metrics`.
This will currently export just the default metrics, like `go_goroutines`, `process_cpu_seconds_total`, `process_open_fds`, and `process_resident_memory_bytes`. Later work will start exporting Boulder-specific metrics, but this will allow Ops to start configuring scraping of Prometheus metrics in production.
Tests pass:
