Running steampipe commands leave behind plugin* unix socket files in $TMPDIR

[pskrbasu]

Running steampipe periodically in a cronjob is leaving plugin* files in the /tmp(or $TMPDIR) dir. It seems like they left-over unix-socket files for the plugin GRPC connections.
Doing ls -al $TMPDIR/plugin* shows the files in your system.

Needs reproduction steps.

Findings/Reproduction:

1. plugin* files present in $TMPDIR
2. Cleared all existing plugin* files
3. steampipe query "select 1"

1 plugin* file got created

4. steampipe service start

quite some plugin* files get created

5. steampipe service stop

Removes plugin* files but leaves 1 behind. Now we have 2 plugin* files(1 plugin* file from step 3)

6. steampipe plugin list

1 plugin* file got created

Every successful command execution leaves behind 1 plugin* file.
