The simple Resmgr API

[robin2008]

To address https://github.ibm.com/xcat2/task_management/issues/271

• remove the MOCK API
• using __TFPOOL-FREE as free pool, and for occupied: __TFPOOL-<username>
• the tags should be define in nodelist.comments as format of tags=[tag1,tag2,tag2]
• enhance auth to put username in g when using token
• refine some format for python3

Prepare the pool as below:

lsdef -t node __TFPOOL-FREE
Object name: node0001
    arch=x86_64
    groups=all,__TFPOOL-FREE
    mtm=fake1
    postbootscripts=otherpkgs
    postscripts=syslog,remoteshell,syncfiles
    rack=N1
    usercomment=tags:[ib,gpu,china]
Object name: node0002
    arch=x86_64
    groups=all,__TFPOOL-FREE
    mtm=fake2
    postbootscripts=otherpkgs
    postscripts=syslog,remoteshell,syncfiles
    usercomment=tags:[ib,gpu,china]
Object name: node000211
    arch=x86_64
    groups=all,__TFPOOL-FREE
    mtm=fake1
    postbootscripts=otherpkgs
    postscripts=syslog,remoteshell,syncfiles
    usercomment=tags:[gpu,china]

Apply with attribute:

curl -X POST "http://10.6.27.1:5000/api/v2/manager/resmgr" -H  "accept: application/json" -H  "Authorization: token c61bdb8a-7c37-11e9-b7ac-0cc47aea9e02" -H  "Content-Type: application/json" -d "{  \"capacity\": 1,  \"criteria_spec\": {     \"machinetype\":\"fake1\"   }}"
{
    "51ba69a0-7c5f-11e9-b2bd-0cc47aea9e02": "node0001"
}

Free specified nodes:

curl -X DELETE "http://10.6.27.1:5000/api/v2/manager/resmgr?names=node0001" -H  "Authorization: token c61bdb8a-7c37-11e9-b7ac-0cc47aea9e02"
null
# lsdef node0001
Object name: node0001
    arch=x86_64
    groups=all,__TFPOOL-FREE
    mtm=fake1
    postbootscripts=otherpkgs
    postscripts=syslog,remoteshell,syncfiles
    rack=N1
    usercomment=tags:[ib,gpu,china]

Free specified nodes with wrong name:

curl -X DELETE "http://10.6.27.1:5000/api/v2/manager/resmgr?names=node000211,abc" -H  "Authorization: token c61bdb8a-7c37-11e9-b7ac-0cc47aea9e02"
{
    "message": "Nodes are not owned by user: test01, no permission to free: abc."
}

Using tags and not enough resource:

curl -X POST "http://10.6.27.1:5000/api/v2/manager/resmgr" -H  "accept: application/json" -H  "Authorization: token c61bdb8a-7c37-11e9-b7ac-0cc47aea9e02" -H  "Content-Type: application/json" -d "{  \"capacity\": 2,  \"criteria_spec\": {     \"machinetype\":\"fake1\",     \"tags\": \"-ib,china\"   }}"

{
    "message": "Not enough free resource matched with the specified attributes."
}

expect the number which meet the pool

curl -X POST "http://10.6.27.1:5000/api/v2/manager/resmgr" -H  "accept: application/json" -H  "Authorization: token c61bdb8a-7c37-11e9-b7ac-0cc47aea9e02" -H  "Content-Type: application/json" -d "{  \"capacity\": 1,  \"criteria_spec\": {     \"machinetype\":\"fake1\",     \"tags\": \"-ib,china\"   }}"
{
    "8b031b48-7c65-11e9-bc76-0cc47aea9e02": "node000211"
}

Good to me, I agree to merge.
