class NsxLibConfig(object):
"""Class holding all the configuration parameters used by the nsxlib code.
:param nsx_api_managers: List of IP addresses of the NSX managers.
Each IP address should be of the form:
[<scheme>://]<ip_adress>[:<port>]
If scheme is not provided https is used.
If port is not provided port 80 is used for http
and port 443 for https.
:param username: User name for the NSX manager
:param password: Password for the NSX manager
:param client_cert_provider: None, or ClientCertProvider object.
If specified, nsxlib will use client cert auth
instead of basic authentication.
:param insecure: If true, the NSX Manager server certificate is not
verified. If false the CA bundle specified via "ca_file"
will be used or if unsest the default system root CAs
will be used.
:param ca_file: Specify a CA bundle file to use in verifying the NSX
Manager server certificate. This option is ignored if
"insecure" is set to True. If "insecure" is set to
False and ca_file is unset, the system root CAs will
be used to verify the server certificate.
:param concurrent_connections: Maximum concurrent connections to each NSX
manager.
:param retries: Maximum number of times to retry a HTTP connection.
:param http_timeout: The time in seconds before aborting a HTTP connection
to a NSX manager.
:param http_read_timeout: The time in seconds before aborting a HTTP read
response from a NSX manager.
:param conn_idle_timeout: The amount of time in seconds to wait before
ensuring connectivity to the NSX manager if no
manager connection has been used.
:param http_provider: HTTPProvider object, or None.
:param max_attempts: Maximum number of times to retry API requests upon
stale revision errors.
:param plugin_scope: The default scope for the v3 api-version tag
:param plugin_tag: The value for the v3 api-version tag
:param plugin_ver: The version of the plugin used as the 'os-api-version'
tag value in the v3 api-version tag
:param dns_nameservers: List of nameservers to configure for the DHCP
binding entries. These will be used if there are
no nameservers defined on the subnet.
:param dns_domain: Domain to use for building the hostnames.
:param dhcp_profile_uuid: Currently unused and deprecated.
Kept for backward compatibility.
