Review request for mesos, Adam B, Jan Schlicht, and Till Toenshoff.


Bugs: MESOS-5707
    https://issues.apache.org/jira/browse/MESOS-5707


Repository: mesos


Description
-------

The fact that not all endpoints can be secure through ACLs, yet
the ACL is called `get_endpoints`, can be confusing for operators.
Therefore, if an operator tries to launch an agent/master with an
invalid configuration an error is generated.

Testing
-------

`make check` and following scripts:

```sh
#! /usr/bin/env bash

rm -rf /tmp/mesos/*

cat <<EOF > /tmp/credentials.txt
foo bar
baz bar
EOF

cat <<EOF > /tmp/acls.json
{
  "permissive": false,
  "get_endpoints" : [
   {
     "principals" : { "values" : ["foo"] },
     "paths" : { "values" : ["/frameworks"] }
   }
  ]
}
EOF

# Fails to start up with a message saying that `/frameworks`
# ins't supported.
./bin/mesos-slave.sh --work_dir=/tmp/mesos/slave \
                     --master=127.0.0.1:5050 \
                     --authenticate_http \
                     --http_credentials=file:///tmp/credentials.txt \
                     --acls=file:///tmp/acls.json &
