[cbq parameters] \set -creds test:'pass:123' in cbq shell:Authorization Failed Keyspace test - cause: Expecting 200 or 401 from ns_server auth endpoint. Got: 500 Internal Server Error"

Found this bug while verifying MB-25167.

1. Install 4.6.3.-4055
2. create a bucket test with password as pass:123,create primary index on it through UI.
3. connect to cbq as:

cbq> [root@localhost bin]# ./cbq

 No input credentials. In order to connect to a server with authentication, please provide credentials.

 ERROR 100 : N1QL: Connection failure Requested resource not found.

 Path to history file for the shell : /root/.cbq_history 

cbq> \connect http://localhost:8091;

 Couchbase query shell not connected to any endpoint. Use \CONNECT command to connect.

 ERROR 100 : N1QL: Connection failure Requested resource not found.

cbq> \connect http://localhost:8093;

cbq> 

4. set creds for the bucket:
\set -creds test:'pass:123';

5. Try to query this bucket.
cbq> select * from test;
{
"requestID": "ed40c8df-658c-430c-9fcd-27b06d45db7c",

6. If I have another bucket bucket0 with password as password then the above steps work for it.

cbq> \set -creds bucket0:password;
cbq> select * from bucket0;
