## Description
This PR adds new authentication method for snowflake: Use of public and
private keys to authorise a snowflake database.
Snowflake provides a couple of authentication mechanisms in order to
authenticate the DB. Currently appsmith only provides a way to authorise
using username and password. This PR adds support for private key
authentication, where by user can set a public key on their DB and they
can use corresponding private key in appsmith to authorise the
datasource.
In snowflake DB form, we have added a new field for authentication type
which has two options: Basic and Key pair. Basic will allows us to
authenticate using username and password. Key pair will provide us a way
to upload the private key along with input field for adding passphrase
(In case of encrypted private key).
