Start bash command blocks at the left margin, removing
excessive padding/indentation that would render the
block too much towards the right.

At the same time ident the source consistently:
- Two spaces for command blocks and output blocks.
- Four spaces for notes, code blocks.

There seems to be no uniform style for this, sometimes
commands are indented with three spaces but it would
seem two spaces is common. In the end it all renders

src/mon/Monitor: Fix set_elector_disallowed_leaders

Problem:

In the monitors we hold 2 copies of disallowed_leader ...
1. MonMap class 2. Elector class.
When computing the ConnectivityScore for the monitors during
the election, we use the `disallowed_leader` from Elector
class to determine which monitors we shouldn't allow to lead.

Now, we rely on the function `set_elector_disallowed_leaders`
to set the `disallowed_leader` of the Elector class, MonMap
class copy of the `disallowed_leader` contains the
`tiebreaker_monitor` so we inherit that plus we also add the
monitors that are dead due to a zone failure.

Hence, the `adding dead monitors` phase is only allowed if we can
enter stretch_mode. However, there is a problem when failing over a stretch cluster
zone and reviving the entire zone back up, the revived monitors
couldn't enter stretch_mode when they are at the state of "probing"
since PaxosServices like osdmon becomes unreadable (this is expected)

Solution:

We unconditionally add monitors that are in
`monmap->stretch_marked_down_mons` to the
`disallowed_leaders` list in
`Monitor::set_elector_disallowed_leaders` since
if the monitors are in `monmap->stretch_marked_down_mons`
we know that they probably belong in a marked down
zone and is not fit for lead.

This will fix the problem of newly revived monitors
having different disallowed_leaders set
and getting stuck in election.
