Support Python SDK 3.0.0

[antonpirker]

[work in progress]

Update the code so it works with the upcoming major release of the Sentry Python SDK 3.0.0.

Sentry SDK 3.0.0 has massive changes on how the data flows through the SDK compared to 2.x. (3.0 uses Opentelementry under the hood to create spans)

Some APIs in 3.0 is not backwards compatible with 2.x so we need to change a lot of call sites.

Todo:

• set_attribute type NOT a dict. (search for TODO-anton in PR files changed)
• attributes in start_span can NOT be a dict.
• change set_span_data() to set_span_attribute() but check for value NOT be a dict.
• make sure traces_sampler works the same as before (check for sample_rate)
• check event["measurements"] places if those can be removed (because SDK does not support measurements anymore)

What this PR does:

• replaced custom_sampling_context with attributes parameter in @trace_func
• replaced with sentry_sdk.init(dsn=...) with with sentry_sdk.new_scope() as scope: scope.set_client(sentry_sdk.Client(dsn=...)) in src/sentry/runner/main.py
• Ignored the access to event["measurements"] in the mypy type checking.
• remove custom_sampling_context everywhere in code base (given to spans)
• removed propagate_hub=True from ThreadingIntegration
• removed the @mmetrics_noop decorator, because there are no metrics anymore only span.data, so we do not need it.
• moved sampled=False from assigning to a span into the start_span() call.
• replaces span.set_data with span.set_attribute with the same params
• changed one scope.add_attachment to sentry_sdk.add_attachment
• changed all .start_transaction() to .start_span() (without ever setting only_if_parent)
• changed custom_sampling_context param in .start_span() to attributes
• changed one continue_trace to the new context manager.
• removed helper src/sentry/utils/sdk.py::set_measurement() because it is not used in sentry.
• replaced scope.transaction with scope.root_span
• replaced sentry_sdk.Scope.get_*_scope() with sentry_sdk.get_*_scope()
