this change is a leftover of 063b3be,
which failed to include the changes in the header files.
it turns out we have `using namespace httpd;` in seastar's
`request_parser.rl`, and we should not rely on this statement to
expose the symbols in `seatar::httpd` to `seastar` namespace.
in this change,
* api/*.hh: all httpd symbols are referenced by `httpd::*`
instead of being referenced as if they are in `seastar`.

Task ttl can be set with task manager test api, which is disabled
in release mode.
Move get_and_update_ttl from task manager test api to task manager
api, so that it can be used in release mode.
Closes#12894
