Change subject: IMPALA-4704: Turns on client connections when local catalog initialized.

Patch Set 19:

File be/src/service/frontend.h:
PS19, Line 162: Sets the FE catalog to be initialized.
> I don't understand what that's trying to say.
updated the comment to better reflect the method renaming.
File be/src/service/impala-server.h:
PS19, Line 79: The executor role starts ImpalaInternalService API's
> technically the coordinator also has to start the ImpalaInternalService API
PS19, Line 89: must call the following
             : /// methods:
> why is this split into two steps? Is there something the caller would want 
good question-- I've kept it the same as before so not sure what the reason was to keep them
separated. currently, there is a check in impalad-main in between init and start, but perhaps
we can do without that.
File be/src/service/

PS19, Line 1937:   RETURN_IF_ERROR(exec_env_->StartServices());

I need it for the statestore subscriber to receive the catalog. L1939 will not work otherwise.
Not sure why tests did not run into any issues. For now, I've separated them so that krpc,
when enabled, starts at the same time as before this change.
