The main is doing flag validation through pflags, then
did further validation by involving the constructors.
With the recent refactor on the commit "Refactor constructors"
in this branch, we moved away from that pattern.
However, it means we reintroduced a log dependency into our
external API, and the external API now had extra validations
regardless of the type.
This is unnecessary, so I moved away from that pattern, and
moved back all the validation into a central place, internal,
which is only doing what kured would desire, without exposing
it to users. The users could still theoretically use the proper
constructors for each type, as they would validate just fine.
The only thing they would lose is the kured internal decision
of validation/precedence.

Without this, a bit of the validation is done in main, while
the rest is done in each constructor.
This fixes it by create a new global constructor in checkers/reboot to
solve all the cases and bubble up the errors.
I prefered keeping the old constructors, and calling them, this
way someone wanting to have a fork of the code could still create
directly the good checker/rebooter, without the arbitrary decisions
taken by the generic constructor.
However, kured is not a library, and was never intended to be
usable in forks, so we might want to reconsider is part 2 of the
refactor.

Without this, the checkers are only shell calls: test -f
sentinelFile, or sentinelCommand.
This changes the behaviour of existing code to test file for
sentinelFile checker, and to keep the sentinel command as
a command.
However, to avoid having validation in the root loop, it moves
to use a constructor to cleanup the code.
