It allows plugin to intercept ssh commands within the SshScope.
It is added to address some limitations of the current
SshCreateCommandInterceptor extension point by allowing:
- to inject the SshSession within the interceptor (impossible with
SshCreateCommandInterceptor being injected just before the
SshContext is created)
- multiple plugins to bind it using DynamicSet bindings
