This speeds up auto-suggestion for metric names in VMUI and Grafana, which use the following query in this case:
/api/v1/label/__name__/values?match[]={__name__=~"*.some_value.*"}
When the user types `some_value` in the query input field.
- Use exact matching by default for the query arg value provided via arg=value syntax at src_query_args.
Regex matching can be enabled by using =~ instead of = . For example, arg=~regex.
This ensures that the exact matching works as expected without the need to escape special regex chars.
- Add helper functions for creating QueryArg, Header and Regex structs in tests.
This improves maintainability of the tests.
- Remove url.QueryUnescape() call on the url in TestCreateTargetURLSuccess(), since this is bogus approach.
The url.QueryUnescape() must be applied to individual query args, and it mustn't be applied to the whole url,
since in this case it may perform invalid unescaping in the context of the url, or make the resulting url invalid.
While at it, properly marshal all the fields inside UserInfo config to yaml in tests.
Previously Header and QueryArg structs were improperly marshaled because the custom MarshalYAML
is called only on pointers to Header and QueryArg structs. This improves test coverage.

If one out of 5 vmstorage nodes is unavailable, then the remaining 4 vmstorage nodes will recieve 1/5=20% increase of workload, not 5%.
If one out of 10 vmstorage nodes is unavailable, then the remaining 9 vmstorage nodes will receive 1/10=10% increase of workload, not 1%.

* app/vmauth: do not increment backend_errors when hitting concurrency limit
Previously, both "vmauth_concurrent_requests_limit_reached_total" and "vmauth_user_request_backend_errors_total" were incremented.
This was based on the assumption that if concurrency limit is hit the backend must be failing to handle the request thus meaning an error.
This assumption does not work in case the endpoint can be overloaded by the misbehaving client sending too many requests within the timeframe.
