SERVER-8169 allow OpenSSL to interactively prompt for private key passphrase

I consolidated all the SSL Manager instances into one instance, so that the user is only prompted once
per process.
The prompt will only appear if the user supplies a certificate with a passphrase via --sslPEMKeyFile
and yet omits --sslPEMKeyPassword
SERVER-7172 Build support for finding a path in a mutable document.
