Parser EtcSshConfigD (spec ssh_config_d) doesn't indicate if collected and no files are present, or if collection disabled.

[jsvob]

Expected behavior

Parser EtcSshConfigD (spec ssh_config_d) has a mechanism to indicate these two separate concepts:

• Collection of specs.ssh_config_d is enabled by insights-client.
• There are files in /etc/ssh/ssh_config.d / there are no files in /etc/ssh/ssh_config.d

Current behavior

Parser EtcSshConfigD (spec ssh_config_d) skips if either of these two conditions happen:

• Collection of specs.ssh_config_d is not enabled by insights-client.
• There are no files in /etc/ssh/ssh_config.d

This makes it impossible to tell whether the collection is disabled (OK thing for one of the consumers of the parser) or whether the contents of /etc/ssh/ssh_config.d were deleted (not OK thing for one of the consumers of the parser).

EDIT: Added the missing word "not" (marked in bold).
