Add common url segments parser

This change is adding helper template function, which can be used both
to validate and read segments from segments_view returned by boost_url
parser. Number of segments is also validated - in case when argument
count differs from them, false will be returned. In case when we want to
validate only existence of a segment, special argument can be passed in
its place: 'anySegment'.

Reasoning why url_view  was chosen instead of strings:
- This way code generation is kept minimal.
- There are multiple parse functions in boost_url with different rules,
  but all of them return url_view. This solution should accommodate
  every use case.

Testing done:
- Unit tests are added, passing.
- Refactored part of telemetry to use this new approach, no regression
  spotted during simple POST/GET tests.
