refactor(runner): adjust max-host-error if gt concurrency (#5633)

Browse Source 
* refactor(common): use `ParseRequestURI` instead when `NormalizeCacheValue`

also it exports the method

Signed-off-by: Dwi Siswanto <git@dw1.io>

* refactor(runner): adjust `max-host-error` if gt `concurrency`

Signed-off-by: Dwi Siswanto <git@dw1.io>

* fix lint

* chore(runner): expose adjusted `max-host-error` value
