Input parameters of passwords and private keys are visible in the UI

[nyuuyn]

Current Behavior:
In some older version parameters which represented passwords (e.g. DBMSPassword) the input field hid the value (e.g. pw is shown as: ********).

Additionally, in older version if a parameter was a PrivateKey (e.g. VMPrivateKey) the input field didn't mess up the PrivateKey from a string perspective (e.g. the private key is broken and can't be used by some artefacts such as the SSH service for virtual machines)

Expected Behavior:
Password parameter values are hidden, PrivateKeys are still valid after pasting them into the field.

Steps to Reproduce:

1. Use any CSAR (e.g. MyTinyTodo with MySQL) which has atleast one Password Parameter
2. Use any CSAR which has a PrivateKey Input Parameter

Other Information:
Params not beeing hidden or well formatted:

Some logs when the private key is really needed:

P.S.: I know we can just escape the returns, but well, does it have to be done?! :P
