[lock] interoperate with Python client

[pmazzini]

I got the following error message while using the library:

strconv.Atoi: parsing \"640f65557dc046648b51a144f37fc95d__lock__0000196658\": invalid syntax"

Which led me to finding python-zk/kazoo#548.

Apparently the Go and Python client libraries use a different prefix and don't work well with each other.

I haven't tested the PR yet. I am putting it up for comments to see if it makes sense.

CI failures don't seem related:

Please provide an upload token from codecov.io with valid arguments

Ok I tested it.

Before:

strconv.Atoi: parsing "8b0a8288f9d544aab408fec25f331907__lock__0000000016": invalid syntax

After:

It properly waits for a lock.

Python client uses a different prefix:

Looks good – thanks for the fix, @pmazzini!

Could you please also add a unit test which would verify parseSeq against both cases.

Registered #20 for the CI failures.

Added :)
