## Description
When we create snowflake datasource with wrong credentials -> test
configuration/query execution takes about 25 seconds to complete and
then throws generic error message of `Unable to create connection to
snowflake URL`. This error message does not provide any action items for
user.
The reason this generic error message gets thrown is because we had set
`initializationFailTimeout` hikari config property to -1, which means it
will create a datasource object but will not create connection to it.
Only when we do testDatasource, we fetch the hikari datasource object
using `getConnection` method. This method tries to establish connection
to database and keeps trying until it is successful or timeout of 25
seconds is reached, that's why in our case hikari would throw
interrupted during connection acquisition exception after 25 seconds and
on our plugin code, we would wrap this up in a generic error message
mentioned above.
The fix is to remove the code where we are setting this
initializationFailTimeout, the default value for this property is 1ms
and what this is does is, it tries to establish connection with
snowflake db within that 1ms and if it can't it throws
PoolInitializationException along with error message sent by snowflake
jdbc driver itself, thus we can use this message to show it in the UI.
This initialization was set to -1 in
[PR](https://github.com/appsmithorg/appsmith/pull/23270) which we had
fixed for handling wrong credentials.
### Steps to test:
1. Create snowflake datasource with wrong credentials (In both basic and
key pair auth)
2. Test the configuration
3. Save the datasources and execute a query on it (check the error
message)
4. Test #16140
5. Test #22035
Fixes #`Issue Number`

Fixes `Issue URL`
