this syntax will set the environment variable MY_KEYWORD to "Hello" for
monitors and alerts in that service.

the function of "get" is to retrieve settings which were parsed by
the config file, and also "internal" variables kept by mon while it is
running, such as the time until the next monitor invocation, alert counts,
etc. technically the "get" command will retrieve any scalar value stored
in %{$watch->{$group}->{$service}}. the environment vars are stored there,
but it's stored as a hash, not a scalar.

maybe the right thing to do here would be to add another command called
"getenv" or something which will return the list of env variables defined
for a service.
