peadm::restore fails when puppet-db export times out

[croddy]

Describe the Bug

When restoring a backup made with peadm::backup that includes a dump of pe-puppetdb, the restore plan uses puppet-db export to save more recent data. In even a modestly-sized installation this export fails consistently for me, causing the plan to fail.

Expected Behavior

I expected the restore plan to disregard the contents of PuppetDB on the target system and simply restore the pg_dump dump made by peadm::backup. If I remove the run_command calls to puppet-db then this works just as I expect.

Steps to Reproduce

1. Make a backup with peadm::backup::backup['puppetdb'] set to true.
2. Restore the backup onto a target with a working and running PuppetDB.

Environment

RHEL 7, XL with replica, two compilers, three agents.

Additional Context

I can see the benefit of exporting PDB, but I think it's undesirable for it to be necessarily tied to whether the plan restores the PDB database dump.
