Jira (PUP-11662) Allow legacy facts to be excluded

Title: Message Title

Josh Cooper updated an issue   Puppet / PUP-11662 Allow legacy facts to be excluded Change By: Josh Cooper Puppet agents send core facts to puppetserver in two forms (legacy and structured). In a default agent install, legacy facts account for 25% of the overall fact data when serialized on the wire. The actual savings depends on the number of mountpoints processors , block devices and network interfaces and processors , since because facter adds one multiple legacy fact facts per instance : {noformat} blockdevice_sda_model => . .. blockdevice_sda_size => 1024209543168 blockdevice_sda_vendor => ... ... processor0 => 11th Gen ... processor1 => 11th Gen ... ... processorN => 11th Gen ... ... ipaddress6_lo => ::1 ipaddress_lo => 127.0.0.1 mtu_lo => 65536 netmask6_lo => ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff netmask_lo => 255.0.0.0 network6_lo => ::1 network_lo => 127.0.0.0 scope6_lo => host {noformat} And legacy facts cause problems for puppetserver when using ERB templates because of the way top-scope variables are bound to instance variables in the scope. See PUP-9577 Most of the puppet ecosystem has moved to structured facts, for example, there is a puppet-lint plugin to find and correct legacy fact usage in puppet code modules : https://github.com/mmckinst/puppet-lint-legacy_facts-check While it's possible to block legacy facts (using facter's block list) it puts the burden on users to make that change. This ticket is to allow the agent to exclude legacy facts that it sends to puppetserver. The default behavior should remain the same in 7.x and in 8.0 we can exclude legacy facts by default (see PUP-11430).
