fix: Connection string with ssl broken for postgres

[alexchaaan]

Connection strings with ssl are sent as sslrootcert, sslcert, sslkey and will be parsed as

  config = {
    sslrootcert: rootcert,
    sslcert: cert,
    sslkey: key,

pg expects ssl configurations sent as

  ssl: {
    ca: rootCert,
    cert: cert,
    key: key,
  }

this change checks for ssl configs parsed from a connection string and changes it to the expected ssl object

this would break several drivers. This is nothing to be fixed on core level but on the individual driver.

i.e. postgres with the native pg driver would break, but also any other library that reads the files itself.
