Add and configure OpenTelemetry for tracing

This will auto-hook into Rails and other libraries to produce traces.

No explicit trace spans are created yet, only automatic instrumentation.

The only explicit configuration is to avoid tracing the /up endpoint
used for health checks. This prevents a large number of unhelpful traces
from being created. All other configuration is provided through
environment variables, specified in `forms-deploy`.

We also disable logging for Rake tasks to avoid cluttering output
when running tasks like database migrations.

Finally, OpenTelemetry is only enabled if the `ENABLE_OTEL` environment
variable is set to "true". This allows us to control whether tracing
is active without changing the code. Again, this is configured in
`forms-deploy` when deploying to different environments.
