fix(report): unify .rst section marks
Unify characters marking section levels,
(at least for methodology Vratko contributed to):
Level 0: ==== Do not use, or use for index.rst only.
(Because git conflicts also create ====.)
Level 1: ^^^^
Level 2: ~~~~
Level 3: ````
Level 4: ____
Level 5: ---- Do not use.
(Because other documents use this as level 0,
and it also appears in tables.)
Change-Id: I10813f718b2ee34d1e34c58e62e88353000340e9
Signed-off-by: Vratko Polak <vrpolak@cisco.com>
(cherry picked from commit 6809aeefd0f2b951cd4861f676ee2dff0df47ff2)
