Smoke tests for different configuration options

[ongrid]

Smoke test should make checks that program is runnable in the following popular combinations of envs:

with MEMBER_PRIV_KEY
    with GAS_LIMIT (assert output of serialized Tx)
    without GAS_LIMIT (assert output of serialized Tx with default value)
    with DAEMON (exit code not asserted, app gets killed)
           with SLEEP (assert sleep seconds text in the output)
    without DAEMON (exit code should be asserted)

without `MEMBER_PRIV_KEY` (assert exit code, assert DRY_RUN mode notification )
