(SUP-2817) Consider the distributed architecture of PE_XL and make log scope configurable

[MartyEwings]

Prior to this commit:

• it was not possible to include pe-psql only nodes in the exporter class
• corrective changes for unused schemas appeared on primary servers and pe-postgres servers
• log dir was locked at /var/log/ scope, this can now be optional set to /var/log/puppetlabs

These results were generated with Rangefinder, a tool that helps predict the downstream impact of breaking changes to elements used in Puppet modules. You can run this on the command line to get a full report.

Exact matches are those that we can positively identify via namespace and the declaring modules' metadata. Non-namespaced items, such as Puppet 3.x functions, will always be reported as near matches only.

Tested the changes in my XL environment and everything worked.

• pe-sql node successfully pulled logs
• no corrective changes were seen on infra nodes
• changed the log dir successfully
• unmounted/mounted separate directories
