environment variables do not work for immuclient and immuadmin commands

[vchaindz]

The environment variables that are listed in the command help are ignored when running immuadmin or immuclient, while the flags -a and -p work.

example: immuadmin

IMMUADMIN_ADDRESS=127.0.0.1
IMMUADMIN_PORT=3322
IMMUADMIN_MTLS=true

Furthermore I would expect the environment variables to be named by the target and not the client.

IMMUDB_ADDRESS=127.0.0.1
IMMUDB_PORT=3322
IMMUDB_MTLS=true

[vchaindz]

works now
