* Breaking change(macros): require explicit name for tracing middleware
Closes: #52
This is suggested by the Opentelemetry spec, which requires "Therefore,
HTTP client spans SHOULD be using conservative, low cardinality names
formed from the available parameters of an HTTP request, such as "HTTP
{METHOD_NAME}". Instrumentation MUST NOT default to using URI path as
span name, but MAY provide hooks to allow custom logic to override the
default span name.
"
* Permit customisation of otel span names via OtelName
* Support for opentelemetry 0.18
* Updated changelog
* Update CI/CD to test 0.18
* Update documentation to use opentelemetry 0.18
* Update to use 0.18 in libs
Provides reqwest-tracing with a trait ReqwestOtelSpanBackend, allowing custom fields/behaviour to be defined.
This is a breaking change as the TracingMiddleware signature now requires you to define a ReqwestOtelSpanBackend to provide it with the desired span behaviour.
