(SUP-3122) Fix PSQL node detection in 2021.5

Added indicator S0038 to check number of environments that are present
in $codedir/environments.
If the number of environments is greater than or equal to 100, then
S0038 resolves to false. Otherwise if there are less than 100
environments, the fact resolves to true.
Added documentation to README and test.

This commit modifies S0022
Previously if end date did not exist or resulted in an invalid date,
Facter would experience a runtime exception and crash.
Additionally, the default behavior was for validity to resolve to
true.
Now pe_status_check.S0022 handles the exception when end date is missing or
results in an invalid date. It prints a Facter warning
message, and the fact resolves to false if end date is missing or
cannot be converted to a date. If license_type is
not Perpetual or Subscription or is missing the S0022 resolves to false.

Previously the grep result, an array, for license_type and end date
would be converted into a string. This commit alters this logic to
capture the first item in the array returned from the grep.
Previously: Date.parse(["end: 2022-05-05\n"])
Now: Date.parse("end: 2022-05-05")
Error handling has been added to account for when license_type is
missing, the first item is nil in the array returned from
File.readlines(license_file).grep(%r{license_type:}).

This commit also modifies the spec test for S0022. Previously the spec
test expected failure if the license file doesn't exist on the machine.
Now the spec test adds a new temporary license file with an end date
that has already passed for the failure condition.

(SUP-3101) Add exception handling and Facter warnings for license_type and end date that do not exist or are invalid.

Prior to this commit, if 'sys/filesystem' failed to load in the fact
resolution, 'puppet facts show' would fail with an empty output. This
would cause problems with `puppet infra run` commands as it uses a
different ruby stack than the puppet-agent. This commit catches the
loaderror and causes any checks that use it to be false.
