[Feature] Add Support for encrypting config fields
While writing intermediate config to submit job via seatunnel client,
we are required to encrypt certain fields like password, auth, username
By Default no encryption would be done, to enable the encryption
provide the following properties
```
seatunnel-web:
datasource:
encryption:
type: your_encryption
keys-to-encrypt:
- password
- auth
```
