IOS XR end-set should not be indented

[mpenning]

As one can see here, hier_config IOS XR diff end-set should not be indented... explicitly, this seems to be (slightly) wrong in hier_config version 2.2.3...

Contents of before.txt...

prefix-set ALL
  0.0.0.0/0 eq 32
end-set
!
prefix-set PEERINGS
  1.1.1.1/32,
  2.2.2.2/32,
  10.0.1.0/24,
  172.16.0.0/12,
  192.168.3.0/26
end-set

Contents of after.txt...

prefix-set ALL
  0.0.0.0/0 eq 32
end-set
!
prefix-set PEERINGS
  1.1.1.1/32,
  172.16.0.0/12,
  192.168.3.0/26
end-set

ciscoconfparse2 uses hier_config for all diffs... The diff end-set is indented when it shouldn't be, but I think that will be cosmetic... sadly I don't have an IOS XR system to test against...

By default, hier_config adds the exit_text at the same level that it's currently at:

https://github.com/netdevops/hier_config/blob/master/hier_config/child.py#L116-L117

        if sectional_exiting and (exit_text := self.sectional_exit):
            yield " " * self.driver.rules.indentation * self.depth() + exit_text

I think we should add a depth option fo the SectionalExitiingRule model:

https://github.com/netdevops/hier_config/blob/master/hier_config/models.py#L35-L37

class SectionalExitingRule(BaseModel):
    match_rules: tuple[MatchRule, ...]
    exit_text: str

The default could be 0 and we could set the value to -1 where the exit text should be unindented.
