feat(eventstore): accept transaction in push (#8945)

# Which Problems Are Solved

Push is not capable of external transactions.

# How the Problems Are Solved

A new function `PushWithClient` is added to the eventstore framework
which allows to pass a client which can either be a `*sql.Client` or
`*sql.Tx` and is used during push.

# Additional Changes

Added interfaces to database package.

# Additional Context
