* update go version to 1.18 for api and sdk, go mod tidy
* removes ioutil usage everywhere which was deprecated in go1.16 in favour of io and os packages. Also introduces a lint rule which forbids use of ioutil going forward.

Licensing recently changed in Consul v1.10 and along with those changes
the client API was updated such that PutLicense and ResetLicense both
immediately return an error to avoid an unecessary round trip that will
inevitably fail.
For reference, see: 08eb600ee5
Unfortunately, this change broke forward compatibility such that a v1.10
client can no longer make these requests to a v1.9 server which is a
valid use case.
This commit reintroduces these requests to fix this compatibility
breakage but leaves the deprecation notices in tact.
