## Description
This PR adds JUnit test cases for snowflake Key auth pair feature added.
Following cases have been added:
- For basic authentication mechanism, when we do datasource create ->
hikari config should have non empty username and password and datasource
object inside hikari config should be null
- For key pair authentication mechanism with valid private key -> hikari
config should have datasource object which is of type
SnowflakeBasicDatasource and username, password should be null.
- For key pair authentication mechanism with invalid private key ->
error should be thrown with appropriate error message
- For key pair authentication mechanism with valid private key ->
SnowflakeKeyUtils.readEncryptedPrivateKey should return valid instance
of PrivateKey class.
Note: Valid private key generated for above test cases is unencrypted
private key (i.e. without passphrase). Adding test cases with private
key having passphrase was a little complex than anticipated, hence will
create a separate task and tackle it separately.
