pgAdmin 4 commit: Adding the timeout for the connection on the configur

Adding the timeout for the connection on the configuration database.

While accessing the configuration database from multiple session, it
results in to the error - OperationError, because - sqlite locks all the
database, and does not allow to access it simultaneously. We added the
timeout to give some time window for accessing it simultaneously.
