Add additional names to custom instrumentation so they can be disabled separately (#139)
* Add hypertrace specific names to instrumentations This will allow us to disable all or specific Hypertrace instrumentations. Signed-off-by: Pavol Loffay <p.loffay@gmail.com> * docs Signed-off-by: Pavol Loffay <p.loffay@gmail.com>

### Disable instrumentation at startup
52+
53+
Instrumentations can be disabled by `-Dotel.instrumentation.<instrumentation-name>.enabled=false`.
54+
55+
The following instrumentation names disable only Hypertrace instrumentations, not core OpenTelemetry:
56+
57+
* `ht` - all Hypertrace instrumentations
58+
* `servlet-ht` - Servlet, Spark Web
59+
* `okhttp-ht` - Okhttp
60+
* `grpc-ht` - Okhttp
61+
62+
The Hypertrace instrumentations use also the core OpenTelemetry instrumentation names so for example
63+
`-Dotel.instrumentation.servlet.enabled=false` disables all servlet instrumentations including core
64+
OpenTelemetry and Hypertrace.
