Spindle could not connect to session

Nobody has claimed this yet.

I'm getting errors in testing and attempted usage that Spindle cannot connect to some session. I'm installing as follows:

```bash
./configure --with-munge-dir=/etc/munge --enable-sec-munge --with-slurm-dir=/etc/slurm --with-testrm=slurm
make
make install
```
And I've tried that with both slurm and openmpi as the "testrm" And then I make the tests

```bash -
cd testsuite
make
./runTests
```
but no matter what I do (using the slurm or openmpi template, both of which I have) I see this error:

```bash
Running: ./run_driver --partial --session
ERROR: Spindle could not connect to session tn2VYQ
```
I saw this same error in trying to just use spindle so I've gone back to the tests to debug. Note that I do have a /tmp area:

```bash
ls /tmp/
ccFjQGLR.s ks-script-eC059Y spin.kT6PPu spin.tn2VYQ spin.Un7RTL yum.log
```

Update: I think it could possibly be that they need to see the same /tmp area - so I'm rebuilding the containers with a shared /tmp area and will report back.

Start by reproducing the failure with the configure commands, then run the testsuite commands in testsuite. Compare the slurm and openmpi templates and investigate the reported shared /tmp possibility. Done means determining why Spindle cannot connect to the session and recording a verified resolution.
