Bug Description

Description:
-------------
Instance reservation update request is accepted even if the value provided for disk_gb,
memory_mb, vcpus greater than the capacity of computehost.

Steps to reproduce:
---------------------
1. blazar host-list
 +----+---------------------+-------+-----------+----------+
 | id | hypervisor_hostname | vcpus | memory_mb | local_gb |
 +----+---------------------+-------+-----------+----------+
 | 1 | <host-name> | 4 | 11941 | 91 |
 +----+---------------------+-------+-----------+----------+

2. update a lease with "memory_mb": 1194444 > 11941

curl -g -i -X PUT http://<host-ip>/reservation/v1/leases/c8239d51-96e1-4c4d-8bee-96c5574a32f0 -H "Accept: application/json" -H "Content-Type: application/json" -H "User-Agent: python-blazarclient" -H "X-Auth-Token: gAAAAABbanlmuoiRv5vQr-s3OV06HV2jLqwSwqleOxXu2lTNHpkvWZboXBg-d0Pd8Xw-NeHLcYuA7mgkpCHNDQ6k3qVJKHJKPFz0N3y-kHokpYuZiierZmigwxlY6AIZWyEQ5xqGtgr2HjfiT_HowiFqldqM_P1P3vguIzOt6uaPSaSRKMAp_j8" -d '{"reservations": [{"id": "1f58aa47-0b34-42c9-af6f-0a6535cbb1dd","memory_mb": 1194444}]}'

-----------------
It should not allow to update greater than capacity available.

Actual result:
-----------------
Blazar server doesn't return any error and accept the update request also successfully updates DB.

This might be resolved by the fix implemented for #1786007, need to test. We should write a Tempest test for this.

I could not reproduce this bug (master branch) but still I agree that some work is needed e.g. by adding more test cases, improving/drafting missing documentation on both server and client sides
