Intention to retire golang-github-siddontang-goredis and golang-github-ledisdb

[Mikel Olasagasti]

Hi SIG,

As proposed a few months ago[1], I would like to retire the
`golang-github-siddontang-goredis` and `golang-github-ledisdb`
packages.

Package `golang-github-siddontang-goredis` has been FTBFS since F39
and has been dead upstream for 6 years. The only package depending on
it is `golang-github-ledisdb`, which has been dead upstream for 4
years also.

Package `golang-github-siddontang-goredis` will be retired at the end
of this month as part of the "List of long term FTBFS packages"
procedure. I would like to retire it before that happens along with
the ledisdb package.

Unless someone opposes it, I'll retire the packages in a week on the 20th.

Regards,
Mikel
