Query parameter value with ":" (colon) is not encoded

[philippeu]

with openfeign 10.2.3

query parameter value with ":" is not encoded , e.g. "url=http://toto.com" produces "url=http:%2F%2Ftoto.com" instead of "url=http%3A%2F%2Ftoto.com".
what i understand from rfc3986 section 2.2 is that ":" should be encoded

URI producing applications should percent-encode data octets that
correspond to characters in the reserved set unless these characters
are specifically allowed by the URI scheme to represent data in that
component. If a reserved character is found in a URI component and
no delimiting role is known for that character, then it must be
interpreted as representing the data octet corresponding to that
character's encoding in US-ASCII.

Note that ":" was encoded in openfeign 10.1.0.

Seems related to refactor done in FragmentType UriUtils.java

This appears to be an issue with our URI template encoding. I'll mark it as a bug and related it to #1019
