fix(is_master-fact): use --ssl if --sslPEMKeyFile or --sslCAFile is s…

[buchstabensalat]

Pull Request (PR) description

When using SSL in any other mode than requireSSL and you have specified a server or ca-certificate the mongodb_is_master fact will fail.

It will generate a shell command like "mongo --quiet --sslPEMKeyFile $file" which results in an
"Failed global initialization: BadValue ssl is required when ssl.PEMKeyFile is specified".

This pull-Request ensures that "--ssl" is also set when setting --sslPEMKeyFile or --sslCAFile.

Hi,

i have changed the mailaddress of the commit.
And I just found a bug that is related to this one.
If the mongodb is bound to 0.0.0.0 or ::0 127.0.0.1 or ::1 is used to connect to the database.
This does not work if ssl/tls is enabled because the local adresses are not part of the certificate (at least if not using self-signed certificates).
I therefore changed it to use the fqdn-address which should work on every system.
