Simple configurable routes mechanism

[Platonn]

It's subtask of #3

This ticket covers only simple configuration mechanism. The config should be provided statically (without getting routes config via http yet - there is other ticket for that).

Acceptance criteria:

• [x] define default urls (even many) for all pages in some default config
• [x] allow extending this config and define custom (even many) urls for each page:
  • for example: someone wants to change 'product/:productCode' url to :productCode/product/:campaignName/:productName (though only :productCode parameter is mandatory, other parameters are only for SEO) and have also a url products/:productCode
• [x] Navigate properly to proper page using defined routes config
• [x] In templates (of navigation and every other component in page) render proper links that are generated basing on page name, routes config and parameters object (ideally parameters object is an entity from data layer) - and to to render this link there is used first path from the list that matches all parameter names with object of parameters
• [x] Provide in the config a mapping of properties names - between entities properties and url's parameter names (for example product entity has a property code, but urls make use of :productCode name)
• [x] Allow defining translations of the routes in routes config (for many languages)

After all many unit/e2e tests should be fixed then, for sure those which:

• used as selectors routerLink='/hardcoded-url'
• navigated to other pages using: router.navigate(), routerService.go() (our facade) or dispatching the action go

❓ Maybe it would be good to have another big happy path e2e tests for using translated routes?

Implementation of simple configurable routes mechanims is already merged into develop for some time.

So I moved out to #564 the acceptance criteria: 'Replace all hardcoded URLs with usages of configurable routes mechanism', which is not merged yet
