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.

* 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:
