tt replicaset roles remove removes roles in the tarantool replicaset with cluster config (3.0) or cartridge orchestrator.

This patch introduces new command for the replicaset module.

$ tt rs roles remove [--cartridge|--config|--custom] [-f] [--timeout secs]
    <APP_NAME:INSTANCE_NAME> <ROLE_NAME> [flags]

It is possible to provide cartridge, config or custom flag to
explicitly state which orchestrator to use. ROLE_NAME is a role to
remove from local cluster config in case of cluster config
orchestrator and directly from all instances of replicaset in case
of cartridge orchestrator. Command supports cartridge and cluster config
orchestrators only for the entire application. INSTANCE_NAME works only
for cluster config to provide instance name to remove role from.

There are flags supported by this command:

• --global (-G) for a global scope to add a role (only for cluster config
  orchestrator);
• --instance (-i) string for an application name target to specify
  an instance to add a role;
• --replicaset (-r) string for an application name target to specify
  a replicaset to add a role;
• --group (-g) string for an application name target to specify a group
  to specify a group to add a role (only for cluster config);
• --force (-f) skips instances not found locally in cluster config orchestrator.

Closes #916
