Plain Text secrets and passwords to be encrypted in memory

[godwinpinto]

Feature:
Currently application takes plain text passwords in variables and keeps them as is during the lifecycle of application. This has security issue where passwords will be revealed during heap dump.
Note: this issue is related to application related secrets only.

Solution:
Use spring password encoders wherever secrets are involved and decode them for temporary use where applicable and clear them / they get cleared due to variable scope completion.
