For historic reasons, we have (in bytes.hh) a type sstring_view which is an alias for std::string_view - since the same standard type can hold a pointer into both a seastar::sstring and std::string.
This alias in unnecessary and misleading to new developers, who might be misled to believe it is assume it is somehow different from std::string_view - when it isn't.
This series removes all uses of sstring_view (changing them to use std::string_view), and in the last patch removes the alias itself. A few functions whose name referred to "sstring" but take a std::string_view were renamed.
The patches are fairly mechanical and trivial, with no functional changes intended. To ease the review the series was split to a few smaller patches that modify specific areas of the code.
Fixes#4062.
